Best Locking Hitch Pin For 2 5 Receiver: 10 Options Compared
A strong locking hitch pin for a 2.5-inch receiver should match the receiver’s pin-hole diameter and provide enough usable span to pass through the receiver and mounted accessory. For a Class V hitch, Rhino USA 2.5-inch Trailer Hitch Pin is the clearest exact-fit choice in this group: it is specifically listed for 2.5-inch hitches, uses solid steel, and includes two keys. Other options cover useful needs, including a stainless-steel lock made specifically for 2.5-inch receivers, longer pins that fit both 2-inch and 2.5-inch receivers, and locks with swivel heads or anti-rattle O-rings.
Check your hitch and accessory dimensions before ordering; receiver size alone does not guarantee the lock’s pin diameter or usable span will fit your setup.
Rhino USA 2.5-inch Trailer Hitch Pin is the best overall choice here because it is specifically designed for 2.5-inch Class V hitches and uses a solid-steel pin. It includes two keys and a dust cover, with an unlimited lifetime warranty listed in its specifications. If you need a lock explicitly described as stainless steel or want an extended span for multiple receiver sizes, consider the other options below, but verify the pin diameter and clearance against your hitch and accessory before buying.

Detailed Reviews: Best Locking Hitch Pin For 2 5 Receiver

#1 · Best Overall
1. Rhino USA 2.5-inch Hitch Pin
- Weight: 15.8 oz
- Material: Carbon Steel
Best for: Class V Receiver Security.
Why it ranks #1: Specifically fits 2.5-inch Class V hitches and uses solid steel; it also includes two keys and a dust cover.
A solid carbon-steel pin gives this Rhino USA lock its clearest advantage: a tamper-resistant barrier for Class V towing setups using a 2.5-inch receiver. Its dust cover helps shield the keyway from debris, while the included two keys make everyday locking and unlocking straightforward.
The 5/8-inch locking pin is specified for 2.5-by-2.5-inch Class V hitches, helping buyers match it to a heavy-duty receiver rather than a smaller opening. Solid carbon steel supplies the stated anti-theft construction, and the dust cover helps keep debris away from the key slot between uses. Two included keys provide a spare for the owner or another driver. The listed fit is specific, so this is not the broadest choice for mixed receiver sizes.
- Fits 2.5-by-2.5-inch Class V receivers
- 5/8-inch locking pin
- Solid carbon-steel construction
- Dust cover and two included keys
- Its listed fit is limited to 2.5-inch Class V receivers.
Skip it if you need one lock for both 2-inch and 2.5-inch receivers; the TowWorks 79631 lists compatibility with both sizes.
Choose this Rhino USA lock for a Class V truck setup where a 2.5-inch receiver, solid-steel pin, and covered keyway suit the routine. Its stated receiver fit is specific, so check that your towing hardware uses the listed 2.5-inch size.

#2 · Made-in-USA Build
2. InfiniteRule 2.5-inch Hitch Lock
- Weight: 10.2 oz
Best for: Machined 2.5-Inch Security.
Why it ranks #2: Designed specifically for 2.5-inch receivers, with stainless steel and a machined threaded locking mechanism described as tamper resistant.
A machined, heavy-duty threaded locking mechanism is the defining feature of this InfiniteRule lock, providing a tamper-resistant approach for standard 2.5-inch receivers. High-grade stainless steel resists rust, and the thick lock cylinder overlaps the pin for an additional layer of physical coverage.
The lock is specified for standard 2.5-inch receivers and Class III, IV, and V applications, making its receiver size the key fit consideration. High-grade stainless steel supplies corrosion resistance for outdoor use, while the 3/8-inch threaded mechanism and machined locking design are presented as strength-focused security features. The thick cylinder overlaps the pin, helping shield it from damage or tampering. Its focused 2.5-inch fit favors owners who prioritize this receiver size over cross-size versatility.
- Fits standard 2.5-inch receivers
- High-grade stainless-steel construction
- Machined threaded locking mechanism
- Thick cylinder overlaps the pin
- Its listed receiver fit is 2.5 inches, not 2-inch receivers.
Skip it if you need one lock for both 2-inch and 2.5-inch receivers; the Vehiclex VHX-HITCH-PIN-LOCK lists both sizes.
This InfiniteRule lock suits owners of 2.5-inch receiver setups seeking stainless construction and a threaded, overlapping-cylinder design. Its stated fit is specific, so it is not the flexible choice for a 2-inch receiver.

3. C.T.Johnson RH5-XL Lock
- Weight: 16 oz
- Material: Carbon Steel
- Material Type: Carbon Steel
Best for: 2.5-Inch Truck Receiver.
Why it ranks #3: The listing explicitly identifies it as a receiver hitch lock for a 2.5-inch receiver, though it provides few other fit details.
The C.T.Johnson RH5-XL is identified for a 2-1/2-inch receiver, making it a narrowly targeted option for truck owners with that receiver size. Its 5/8-inch hitch-lock specification and carbon-steel material provide the available hardware details for buyers comparing basic locking-pin compatibility.
C.T.Johnson identifies the RH5-XL as a receiver hitch lock for a 2-1/2-inch receiver, and the specifications list truck compatibility. That gives truck owners a clear receiver-size starting point when selecting a lock for a larger hitch opening. The 5/8-inch designation describes the pin size, while carbon steel names its material. The supplied product details do not list a shaft span, key count, or operating mechanism, so buyers focused on those particulars have less information here.
- Identified for 2-1/2-inch receivers
- 5/8-inch hitch-lock specification
- Carbon-steel material
- Listed compatible vehicle type is truck
- The supplied details do not specify shaft span or key count.
Skip it if you need a stated shaft length and key count; the Rhino USA 2.5-inch lock lists two keys and a dust cover.
This C.T.Johnson lock is best considered by truck owners matching a 2.5-inch receiver and 5/8-inch pin. Its supplied listing is sparse on operating details, so it may not suit buyers who need those specifics upfront.

#4 · Extended-Span Fit
4. TowWorks 79631 Hitch Lock
- Material: Steel
- Material Type: Steel
Best for: Mixed-Size Receiver Flexibility.
Why it ranks #4: Its 5/8-inch pin has a 3-1/4-inch maximum active length and is listed for both 2-inch and 2.5-inch receivers.
An extra-long 3-1/4-inch active span lets the TowWorks 79631 cover both 2-inch and 2.5-inch receivers, giving owners of different Class III or IV setups one locking pin option. Its separate spring clip adds a secondary securing step, while rubber O-rings help control rattling.
The 5/8-inch pin and stated 3-1/4-inch active length support use in Class III and IV receivers sized 2 or 2.5 inches, useful when a vehicle or accessory setup changes. Its steel construction has zinc plating internally and black electrophoresis externally, surface treatments intended to resist rust. O-rings hold the pin still and reduce rattles; the separate cotter-style spring clip must also be used, making it an important part of the securing routine.
- Fits 2-inch and 2.5-inch Class III/IV receivers
- 3-1/4-inch maximum active span
- Steel pin with zinc-plated and black electrophoresis finishes
- O-rings reduce rattling and a spring clip adds security
- The spring clip must be used, adding a separate step to installation.
Skip it if you want a lock-only installation without a required spring clip; the CURT 23504 uses a locking pin without that listed extra step.
This TowWorks pin suits owners moving between 2-inch and 2.5-inch Class III or IV receivers who value span flexibility and rattle control. Remember to use its required spring clip whenever securing the pin.

#5 · Anti-Rattle O-Rings
5. Vehiclex Hitch Pin Lock
- Weight: 1.25 lb
Best for: Anti-Rattle Mixed-Size Setup.
Why it ranks #5: Fits 2-inch and 2.5-inch receivers with a 3-1/8-inch effective span; five rubber O-rings help reduce rattling.
Five adjustable rubber O-rings give the Vehiclex lock a practical edge for owners who want to tune pin movement and reduce receiver rattling. Its 3-1/8-inch effective span is listed for 2-inch and 2.5-inch receivers, while a rubber cap shields the key slot from grime and mud.
Vehiclex specifies a 5/8-inch pin with a 3-1/8-inch effective span for 2-inch and 2.5-inch receivers, giving one lock broader stated size coverage for bike racks, trailers, campers, and cargo carriers. Five O-rings adjust to receiver size and are intended to eliminate rattling, which can make an accessory feel more settled in use. Carbon steel with black electrophoretic paint resists corrosion, and the protective key-slot cap helps keep dust, grime, and mud away.
- 3-1/8-inch effective span for 2-inch and 2.5-inch receivers
- Five O-rings adjust to receiver size
- Carbon steel with black electrophoretic paint
- Protective cap covers the key slot
- The listed compatible receiver sizes are 2 inches and 2.5 inches, not larger sizes.
Skip it if you need a lock for a 3-inch or 3.5-inch receiver; the METOWARE 47267 lists compatibility up to 3.5 inches.
Pick the Vehiclex lock for a 2-inch or 2.5-inch receiver when adjustable O-rings and a covered keyway fit your needs. Its listed effective span and receiver sizes make it a poor match for larger openings.

#6 · Stainless-Steel Pin
6. Master Lock 1469DAT
- Weight: 14.4 oz
- Material: Stainless Steel
- Material Type: Stainless Steel
Best for: Corrosion-Resistant Extended Reach.
Why it ranks #6: Its 5/8-inch pin has a 3-1/2-inch shaft and is listed for 2-inch and 2.5-inch hitches, with stainless-steel construction.
A 3-1/2-inch stainless-steel shaft gives the Master Lock 1469DAT extended reach across 2-inch and 2.5-inch hitches. Stainless construction resists corrosion, while its swivel head turns for easier key access and push-to-lock activation simplifies securing the pin after positioning it.
The 5/8-inch pin and 3-1/2-inch shaft are specified for late-model trucks with heavy-duty tow packages and fit both 2-inch and 2.5-inch hitches. That extended length offers useful reach across these receiver sizes, while stainless steel resists corrosion in outdoor towing use. A swivel head can rotate toward an accessible position, and push-to-lock operation avoids a separate key step when locking. It is a focused choice for compatible receivers rather than a multi-size heavy-duty option.
- 3-1/2-inch shaft fits 2-inch and 2.5-inch hitches
- Stainless-steel construction resists corrosion
- Swivel head allows key access positioning
- Push-to-lock activation
- Its stated fit covers 2-inch and 2.5-inch hitches, not 3-inch or larger receivers.
Skip it if you tow with a 3-inch or 3.5-inch receiver; the METOWARE 47267 lists compatibility with those larger sizes.
This Master Lock suits drivers of compatible trucks, trailers, or RVs who want stainless construction and a swivel head for easier access. Its listed receiver range stops at 2.5 inches, which matters for larger setups.

7. CURT 23504 Hitch Lock
- Material: Carbon Steel
- Material Type: Carbon Steel
Best for: Easy-Access Locking Operation.
Why it ranks #7: The 5/8-inch pin fits 2-inch or 2.5-inch receivers, and its right-angle swivel head provides easier keyhole access.
A swivel head and 1/4-turn activation make the CURT 23504 especially practical when key access around the receiver is awkward. Its 5/8-inch carbon-steel pin is listed for 2-inch and 2.5-inch receivers, giving owners of either size a simple way to lock a ball mount or hitch-mounted accessory in place.
The right-angle design puts the swivel head at the receiver, where it can rotate toward the user for easier locking and unlocking access. A quarter-turn activates the lock, simplifying operation once the 5/8-inch pin is in place. CURT lists compatibility with 2-inch and 2.5-inch receivers, and carbon steel provides the stated high-strength construction. The lock secures a ball mount or accessory against removal, but CURT expressly notes it does not eliminate receiver play, looseness, or rattling.
- Right-angle design with swivel head
- 1/4-turn lock activation
- 5/8-inch pin for 2-inch or 2.5-inch receivers
- Carbon-steel construction
- It does not eliminate receiver play, looseness, or rattling.
Skip it if you want a pin specifically described with O-rings to reduce rattles; the TowWorks 79631 includes six O-rings for that purpose.
Choose the CURT for compatible 2-inch or 2.5-inch receivers when access and quick quarter-turn operation matter. It secures the mounted accessory against removal, but is not a fix for receiver looseness or rattling.

8. METOWARE 47262 Hitch Lock
- Weight: 0.45 kg
- Material: Alloy Steel
- Material Type: Alloy Steel
Best for: Quick Push-to-Lock Convenience.
Why it ranks #8: This 5/8-inch locking pin is listed for 2-inch and 2.5-inch receivers and uses a push-to-lock mechanism with two keys.
Push-to-lock operation lets the METOWARE 47262 secure the pin without using a key, streamlining installation when hitching up. The 5/8-inch alloy-steel lock is listed for 2-inch and 2.5-inch receivers, and two alike tubular keys are included for unlocking when it is time to unhitch.
The push-to-lock mechanism allows the user to lock the pin without inserting a key, which can speed setup at the receiver. METOWARE lists compatibility with 2-inch and 2.5-inch receivers and identifies alloy steel as the material, making it relevant to common towing-truck and car applications. Two alike tubular keys are supplied for unlocking, so either key can serve the same lock. This combination suits routine attachment changes, while the stated receiver range does not extend to larger sizes.
- Push-to-lock operation requires no key to lock
- 5/8-inch pin listed for 2-inch and 2.5-inch receivers
- Alloy-steel construction
- Two alike tubular keys included
- Its listed receiver compatibility stops at 2.5 inches.
Skip it if you use a 3-inch or 3.5-inch receiver; the METOWARE 47267 lists fit through 3.5 inches.
Pick this METOWARE lock for 2-inch or 2.5-inch towing setups where key-free locking speeds hitch changes. The two alike keys handle unlocking, but its stated compatibility does not cover larger receiver sizes.

View on AmazonWhy it ranks #9: Its 5/8-inch, 4-inch-long pin covers 2-inch through 3-1/2-inch receivers, but the broad fit makes exact clearance worth checking.
A 4-inch-long, 5/8-inch pin is the defining feature of this METOWARE lock, with listed compatibility spanning 2-inch through 3-1/2-inch Class III, IV, and V receivers. That broad range makes it relevant for owners whose towing hardware includes larger receiver sizes as well as common 2-inch openings.
METOWARE lists compatibility with 2-inch, 2.5-inch, 3-inch, and 3.5-inch Class III, IV, and V receivers, so the 4-inch pin length addresses a wider range than locks limited to the smaller sizes. The all-metal construction is described as heavy duty, and two tubular keys support locking and detaching the pin. This range can simplify choosing one lock across different receiver classes, but the listed dimensions should be matched to the actual hitch before installation.
- 4-inch-long, 5/8-inch hitch pin
- Lists fit for 2-inch through 3.5-inch receivers
- Compatible with Class III, IV, and V hitches
- Two tubular keys included
- Its stated maximum receiver size is 3.5 inches.
Skip it if you use only a 2.5-inch receiver and want a more compact, specified span; the Vehiclex 3-1/8-inch pin lists that size.
Consider this METOWARE lock if your towing equipment spans several receiver sizes, including 3-inch or 3.5-inch openings. Its broad listed compatibility is useful, but confirm the pin dimensions against the specific receiver before use.

View on AmazonWhy it ranks #10: This keyed-alike two-lock set is described for 2-inch and 2.5-inch receivers, but the supplied specifications give few fit dimensions.
Two keyed-alike locks let the Orion Motor Tech set secure a receiver and adjustable ball mount at the same time, with one key system for both. Its 5/8-inch pins are listed for 2-inch and 2.5-inch receivers, giving owners of those sizes a paired security setup.
The two-pack’s keyed-alike arrangement means the included keys work with both locks, simplifying access when one pin secures the receiver and the other an adjustable ball mount. The title specifies 5/8-inch pins for 2-inch and 2.5-inch receivers, covering two common sizes. A hardened steel core and drop-proof construction address resistance to prying and tampering, while the stated use includes securing equipment during storage or travel. This format is particularly useful when two locking points are needed.
- Two locks included
- Keys work with both locks
- 5/8-inch pins for 2-inch and 2.5-inch receivers
- Hardened steel core and drop-proof design
- The set is specified for 2-inch and 2.5-inch receivers, not larger sizes.
Skip it if you need a lock for a 3-inch receiver; the METOWARE 47267 lists compatibility with receivers up to 3.5 inches.
Choose this Orion Motor Tech set when you need two locking points for a receiver and adjustable ball mount, and prefer shared keys. Its stated 2-inch and 2.5-inch fit limits its relevance for larger receivers.

View on AmazonAvoid a fit problem at the pin hole
A 2.5-inch receiver label alone does not confirm that a locking pin will fit your complete hitch setup. Several picks list a 5/8-inch pin, including Rhino USA 2.5-inch Hitch Pin, TowWorks 79631 Hitch Lock, and Master Lock 1469DAT, but usable span differs: TowWorks lists a 3-1/4-inch maximum active length, while Master Lock lists a 3-1/2-inch shaft. Vehiclex Hitch Pin Lock gives a 3-1/8-inch effective span.
These measurements are not necessarily interchangeable, so check what each product calls its measurement and compare it with the receiver, ball mount, or accessory. A pin that reaches through the receiver but not through the accessory’s aligned holes cannot secure the assembly.
Confirm the receiver’s pin-hole diameter and the required clearance before ordering, especially when using an unusually thick mount or an extended receiver.
Security locks do not all control rattling
A locking pin can deter removal, but it does not automatically eliminate receiver play. CURT 23504 Hitch Lock specifically says it is not designed to eliminate looseness or rattling, a useful distinction when choosing between security and noise control. Vehiclex Hitch Pin Lock includes five rubber O-rings intended to adjust to receiver size and reduce rattling; TowWorks 79631 Hitch Lock includes six O-rings and says its spring clip must be used.
These features address movement differently from the lock cylinder itself. Do not treat an anti-rattle feature as proof that a pin fits every receiver or that a lock prevents all movement.
First confirm dimensional fit and installation requirements, then choose O-rings if reducing pin movement matters. If the accessory still shifts, the receiver connection may need a separate compatible anti-rattle solution.
How to Choose a 2.5-Inch Hitch Lock
Receiver and pin dimensions
Look for a pin diameter and usable span that match both the receiver and the accessory. Several products specify a 5/8-inch pin, including Rhino USA 2.5-inch Hitch Pin, TowWorks 79631 Hitch Lock, Vehiclex Hitch Pin Lock, and Master Lock 1469DAT. Listed spans vary: Vehiclex gives 3-1/8 inches effective, TowWorks gives 3-1/4 inches maximum active length, and Master Lock lists a 3-1/2-inch shaft.
Rhino USA is specifically for 2.5-inch hitches, while several alternatives cover both 2-inch and 2.5-inch receivers. An exact-fit 2.5-inch buyer should start with the dedicated option; someone sharing a lock across receiver sizes may prefer a listed multi-size fit, after checking clearance.
Construction and weather protection
Choose a construction and protective design that suit how and where you use the hitch. Rhino USA 2.5-inch Hitch Pin specifies carbon steel and a dust cover; InfiniteRule 2.5-inch Hitch Lock lists stainless steel and describes its design as corrosion resistant and weatherproof. Master Lock 1469DAT also specifies stainless steel, while TowWorks 79631 Hitch Lock lists steel with zinc plating and a black external finish.
These descriptions differ, and the supplied information does not establish a comparative corrosion test. For frequent outdoor exposure, a listed weather-resistant finish or stainless-steel construction may be appealing; for a straightforward exact 2.5-inch match, Rhino USA offers a dust cover and solid-steel construction.
Inspect and maintain the lock according to its instructions, whatever material you select.
Access, keys, and extra features
Prioritize the operating details that make locking and removal practical in your setup. CURT 23504 Hitch Lock uses a swivel head and 1/4-turn activation, while METOWARE 47262 Hitch Lock uses push-to-lock operation and includes two tubular keys. Rhino USA 2.5-inch Hitch Pin also includes two keys.
TowWorks 79631 Hitch Lock adds a separate spring clip that its listing says must be used, and its package includes O-rings. Orion Motor Tech Hitch Pin Set is a two-lock, keyed-alike set, useful when you want one key to operate both included locks.
Choose a swivel head where key access is awkward, a two-lock set when securing two points matters, or a simpler single lock when the exact receiver fit is the main priority.
Which 2.5-Inch Hitch Lock Should You Choose?
Choose Rhino USA 2.5-inch Hitch Pin if you want a dedicated 2.5-inch Class V fit, solid-steel construction, two keys, and a dust cover. For a stainless-steel lock specifically designed for 2.5-inch receivers, InfiniteRule 2.5-inch Hitch Lock is the closest alternative. If you need extra listed span and compatibility with both 2-inch and 2.5-inch receivers, compare TowWorks 79631 Hitch Lock and Master Lock 1469DAT, checking their span descriptions against your mount.
Pick Vehiclex Hitch Pin Lock if its 3-1/8-inch effective span suits your setup and O-rings are useful for reducing rattling. For easier key access, consider CURT 23504 Hitch Lock’s swivel head.
In every case, verify pin-hole diameter and clearance before purchase.
Frequently Asked Questions
How do I measure the usable span needed for my 2.5-inch receiver hitch lock?
Measure across the receiver and the hitch accessory at the pin-hole location, including the space the lock head must clear. Compare that distance with the lock’s listed usable span, not just its overall length. Check the fit with your accessory in place, since mounts can change the clearance needed.
Can a 5/8-inch locking pin fit every 2.5-inch receiver and hitch accessory?
No. A 5/8-inch pin must match the pin holes in both the receiver and accessory, and the lock must have enough usable span to pass through them and clear the lock head. Confirm the hole diameter, receiver compatibility, and clearance for your specific setup before choosing a pin.
How can I reduce hitch-pin rattling without compromising a secure fit?
Choose a lock that fits the receiver and accessory securely, and confirm the pin passes fully through both pin holes and the lock engages. Vehiclex’s listing mentions O-rings, which may help reduce rattling. Do not use spacers or other additions that prevent full pin engagement or interfere with locking.
Which listed options are described as stainless steel?
The Master Lock 1469DAT title describes a stainless-steel barbell hitch pin, and the 2.5-inch receiver hitch lock title specifies stainless steel. The editorial verdict also identifies InfiniteRule as a stainless-steel option designed for 2.5-inch receivers. Check the individual listing details and confirm fit before selecting one.
What should I check about keys and included features before buying?
Check the product details for what is included rather than assuming all locks come with the same accessories. The Rhino USA listing specifies two keys and a dust cover, and its specifications list an unlimited lifetime warranty. For other options, verify key and accessory details in their own listings.
Final Words
For a dedicated 2.5-inch Class V setup, the Rhino USA pin is the clearest overall choice in this group: its listing specifies solid steel, two keys, and a dust cover. Consider InfiniteRule if stainless steel is a priority, or compare TowWorks and Master Lock when extra span or dual receiver compatibility matters. Before deciding, confirm pin-hole diameter and usable clearance with your accessory installed.
