• Material: Alloy Steel
• Compatible with Vehicle Type: ATV, Marine-Personal-Craft, Pickup Trucks…
• Material Type: Alloy Steel

Best for: Six-thousand-pound two-inch couplers.

Why it ranks #1: Its 2-inch ball fits matching couplers, while the hot-forged steel ball is rated for 6,000 pounds and has a 1 x 2-1/8-inch shank.

Hot-forged steel and a 6,000-pound gross trailer weight rating make the CURT 40004 a practical match for substantial loads using a 2-inch coupler. Its 1-inch-diameter, 2-1/8-inch-long shank provides the specified connection dimensions for a compatible trailer hitch ball mount.

The 2-inch ball diameter fits 2-inch couplers, while the 1-inch shank and 2-1/8-inch length identify the mount connection dimensions to check before installation. Hot-forged alloy steel supports the 6,000-pound gross trailer weight rating, giving buyers a clear load ceiling for matching a trailer and tow setup. The chrome ball is listed as corrosion-resistant, a useful surface consideration for a component exposed during towing. This package includes a 2-inch trailer ball.

Skip it if you need a 2-5/16-inch coupler or a higher rating; CURT 40007 has that ball size and a 10,000-pound rating.

#2 · Highest Capacity

2. CURT 40030

• Material: Alloy Steel
• Compatible with Vehicle Type: Trailer
• Material Type: Alloy Steel

Best for: Heavy-duty 2-5/16-inch towing.

Why it ranks #2: The 2-5/16-inch ball is rated for 15,000 pounds and uses a substantial 1-1/4 x 2-5/8-inch shank; verify mount thickness and hole limits.

A 15,000-pound gross trailer weight rating makes the CURT 40030 the highest-rated ball in this group, with hot-forged, heat-treated steel for heavy-duty towing. Its 2-5/16-inch ball fits matching couplers, while its large threaded shank requires a suitably sized mount.

The 2-5/16-inch ball matches couplers of that diameter, and the 1-1/4-inch-diameter, 2-5/8-inch-long threaded shank defines the mount connection. CURT specifies a mounting platform at least 3/8 inch thick and a mounting hole no more than 1/16 inch larger than the shank diameter, so installation depends on those dimensions. Hot-forged, heat-treated steel supports the 15,000-pound gross trailer weight rating, setting the load ceiling for compatible equipment.

Skip it if you have a mount that cannot accept a 1-1/4-inch shank; CURT 40007 uses a 1-inch shank for a different capacity class.

This ball suits heavy-duty towing with a 2-5/16-inch coupler when the load stays within 15,000 pounds and the mount meets its platform and hole requirements. Verify those installation dimensions before selecting it.

The 2-5/16-inch ball diameter is the match for a 2-5/16-inch coupler, so coupler size is a first selection check.

10. CURT 42225 Switch Ball Set

• Material: Alloy Steel
• Compatible with Vehicle Type: Trailer
• Material Type: Alloy Steel

Best for: Changing coupler sizes.

Why it ranks #10: Its interchangeable 1-7/8-, 2-, and 2-5/16-inch balls suit varied couplers, but the listing gives no towing capacity or shank dimensions.

Three switchable ball diameters—1-7/8, 2, and 2-5/16 inches—let the CURT 42225 cover different coupler sizes with one set. Its exclusive J-groove design secures the switch-ball system, and the listing says no tools, coins, or pins are required for installation.

The three included ball sizes cover 1-7/8-, 2-, and 2-5/16-inch couplers, which can simplify switching among trailers with those coupler dimensions. CURT’s J-groove design is specified to ensure a secure system, while the no-tools, coins, or pins installation claim can make ball changes less involved. The shank bears the weight, freeing the coupler from friction and binding. High-strength steel is listed for the set; no towing capacity is provided in the supplied facts.

Skip it if you need a stated towing-capacity rating; CURT 40007 lists a 10,000-pound rating for its 2-5/16-inch ball.
