Best RV Jack Blocks for Travel Trailers and Campers

#1 · Best Overall

1. EKON OX BLOX

• Load Capacity: 10000 lb
• Material: Plastic
• Dimensions: 9.29 x 11.89 x 6.5 in

Best for: High-capacity mixed-jack support.

Why it ranks #1: Its 10,000-pound-per-block rating and compatibility with tongue, post, foot, scissor, and stabilizer jacks suit a broad range of RV setups.

A 10,000-pound rating per block gives the EKON OX BLOX a clear role supporting heavy trailer and RV jacks. Its patented design is specified for gravel, grass, dirt, and pavement, letting owners use the same block across varied campsite surfaces and several jack styles.

Compatibility covers tongue, post, foot, scissor, and stabilizer jacks, with round or square feet, so the block can serve different support points across travel trailers, fifth wheels, and other trailers. The 9.29-by-11.89-inch footprint and 6.5-inch height provide a substantial platform without requiring a separate listed block for each jack shape. Made from 100% recycled plastic using compression molding, it pairs a stated 10,000-pound capacity with a material and process intended for rugged use.

Skip it if you need a four-block set supplied together; VEVOR's CXFC02 package includes four blocks.

Choose the OX BLOX for a high-capacity individual support block that must work with varied jack types and campsite surfaces. Its 6.5-inch height and 8.8-pound weight are relevant handling considerations.

#2 · Tall Four-Pack

2. Florety Trailer Jack Block

• Load Capacity: 10000 lb
• Material: Polypropylene
• Dimensions: 12.5 x 12.5 x 8 in

Best for: Broad-foot heavy trailer support.

Why it ranks #2: Four 8-inch-high blocks are each listed at 10,000 pounds, giving buyers multiple tall supports for a trailer or fifth wheel.

A 10,000-pound rating per block pairs with a large 12.5-inch-square base in this Florety four-pack. The broad platform is specified to support the entire foot of camper leveling jacks, giving owners of travel trailers, fifth wheels, and campers a substantial support surface.

Four polypropylene blocks provide multiple support points, and the stated 10,000-pound capacity applies to each block. The large top can support an entire leveling-jack foot, while the round base and side notches near the top are described as helping stability and gripping. At eight inches high, each block offers elevated support; the supplied facts do not state a stacked-load rating, so owners should use the per-block rating as the available capacity information.

Skip it if you want an explicit 6,000-pound per-block rating and a four-block set; VEVOR's CXFC02 lists both.

Florety suits owners seeking four broad, eight-inch-high supports with a 10,000-pound rating per block. Its large top is useful for full jack-foot contact, but the supplied facts give no stacked-load rating.

#3 · Magnetic Two-Pack

3. Andersen Hitches Trailer Jack Blocks 2-Pack

• Load Capacity: 8000 lb
• Material: Plastic
• Dimensions: 12 x 12 x 8 in

Best for: Two-point magnetic support.

Why it ranks #3: Two blocks provide magnetic jack-pad positioning and an 8,000-pound single-stack rating per block for multi-jack campsite setups.

Two blocks with built-in magnets let the Andersen Hitches 3608 set support multiple stabilizer jacks while helping keep each block attached to its jack pad. Each is rated for 8,000 pounds single stacked, giving the pair a useful role in campsite setup.

The magnets connect directly to jack pads, helping maintain positioning as owners lower stabilizers; having two blocks on hand supports more than one point during setup. Each block measures 12 by 12 by 8 inches and is rated for 8,000 pounds single stacked, while double stacking carries a 1,500-pound rating. The product specifications identify compatibility with jack pads up to nine inches round, making pad size a relevant fit consideration before use.

Skip it if you need only one block and want a 12-inch base with an eight-inch profile; Andersen Hitches 3608 single-pack offers that format.

Choose this two-pack if magnetic positioning and support at multiple stabilizer points matter at your campsite. Its stated compatibility is for jack pads up to nine inches round, and stacked use has a lower rating.

#4 · Magnetic Single

4. Andersen Hitches Trailer Jack Block

• Load Capacity: 8000 lb
• Material: Plastic
• Dimensions: 12.28 x 12.28 x 8.7 in

Best for: Magnetic round-pad positioning.

Why it ranks #4: The single block has a built-in magnet, an 8,000-pound single-stack rating, and an 8-inch profile for compatible jack pads.

A built-in magnet on the top holds this Andersen Hitches block against a round trailer jack pad as the jack lowers. That positioning feature helps keep the block under the pad during setup, while the eight-inch height and wide 12-inch base offer a tall support platform.

The single block is rated for 8,000 pounds when used alone, while its double-stacked rating is 1,500 pounds; those figures give buyers distinct limits for either arrangement. Its magnet connects directly to a round jack pad to resist shifting during lowering, reducing the need to reposition the block in that workflow. The 12-inch base and eight-inch profile suit owners seeking elevated jack support, and the package is one block rather than a multi-block set.

Skip it if you need two blocks supplied together; Andersen Hitches 3608 two-pack provides a pair with built-in magnets.

This single block suits owners who value magnet-assisted positioning under a round jack pad and need an eight-inch support height. Its separate, lower double-stack rating matters if you plan to stack blocks.

5. ROBLOCK Trailer Jack Blocks

• Load Capacity: 4E+4 lb
• Material: Plastic
• Dimensions: 11.6 x 11.6 x 6 in

Best for: Jack variety with carry bag.

Why it ranks #5: This four-piece set includes a carrying bag and supports several jack-foot styles; its listing states a 40,000-pound capacity per block.

Compatibility with tongue jacks, wheel jacks, round fifth-wheel feet, and scissor stabilizers makes the ROBLOCK set useful when a rig has varied support hardware. Four six-inch-high blocks come with a bag, while the listed capacity is 40,000 pounds per block.

The high-performance polymer includes anti-UV aging additives and is specified to resist dirt, grime, and oil, connecting material choice to outdoor storage and repeated campsite use. Four blocks and a bag provide an organized way to carry the set, and the 11.6-inch-square, six-inch-high shape establishes its footprint and elevation. Broad jack compatibility includes round and square support styles, so owners can use the same set at multiple compatible support points.

Skip it if you need a stated magnetic connection to a round jack pad; Andersen Hitches 3608 blocks have built-in magnets.

Consider ROBLOCK if your trailer uses varied jack styles and you want four six-inch blocks stored in a bag. Check that the block dimensions suit your storage space and support setup.

6. VEVOR Trailer Jack Block 4-Pack

• Load Capacity: 6000 lb
• Material: Polypropylene T30
• Dimensions: 9.65 x 9.65 x 8.03 in

Best for: Four-block leveling setup.

Why it ranks #6: Four polypropylene blocks are listed at 6,000 pounds each, with stackable height adjustment for trailer and camper jack support.

Four blocks supplied together give the VEVOR CXFC02 a practical edge for owners setting up several support points in one trip. Each polypropylene T30 block is rated for 6,000 pounds, and the stackable format lets campers adjust support height on uneven ground.

The package includes four blocks and instructions, so owners have multiple supports at hand without assembling a complex installation; the product description says they can be positioned in minutes. Stacking lets users adjust height to terrain, while the stated 6,000-pound capacity per block sets a clear support rating. Measuring 9.65 inches square and 8.03 inches high, each block provides a defined footprint for trailer jacks, with polypropylene T30 construction specified for the set.

Skip it if you need a stated 10,000-pound capacity per block; EKON OX BLOX is rated to that figure.

This set suits RV and trailer owners who want four stackable supports for campsite leveling and a stated capacity for each block. Consider its 6,000-pound rating when choosing support for your rig.

7. VEVOR Trailer Jack Blocks 2-Pack

• Load Capacity: 6000 lbs
• Material: PP
• Dimensions: 9.45 x 9.45 x 5.98 in

Best for: Six-inch blocks for rough ground.

Why it ranks #7: Two 6-inch-high blocks are listed at 6,000 pounds each and fit round or square jack legs, support wheels, and insertable legs.

Six-inch-tall cylindrical blocks give the VEVOR CXFC04-2 more elevation than a thin pad, with the product description pointing to gravel, dips, and rough surfaces. Each of the two polypropylene blocks is rated for 6,000 pounds.

The pair provides two support units, each with a stated 6,000-pound capacity, while the taller cylindrical shape is described as increasing support area on uneven or soft ground. Universal compatibility covers round and square metal jack legs, trailer support wheels, and insertable legs, allowing the blocks to serve several listed support styles. At 9.45 inches across and 5.98 inches high, their dimensions indicate a substantial footprint and near-six-inch profile for RV setup.

Skip it if you need four blocks in one package; VEVOR's CXFC02 supplies four stackable supports.

This pair suits RV owners seeking near-six-inch support for varied jack legs and rough or soft ground. The two-block package may not cover as many support points as a larger set.

8. Tlaleikejia Trailer Jack Block

• Load Capacity: 24000 lb
• Material: Heavy-duty Plastic
• Dimensions: 1 x 1 x 1 in

Best for: Four-piece stackable support.

Why it ranks #8: The four-block set is described as stackable and lists 6,000 pounds per block, though its specification dimensions are not useful for fit checks.

Four stackable blocks rated for 6,000 pounds apiece give the Tlaleikejia set a defined capacity for trailer support. The polypropylene T30 construction and stackable format offer campers a way to build support height while carrying several blocks for setup.

Each block is listed at 6,000 pounds, and the product title identifies a four-piece set, giving buyers both a per-block figure and multiple support units. The stackable design is paired with stated dimensions of 9.65 by 9.65 by 8 inches in the feature description, which defines the intended block footprint and height. Polypropylene T30 is specified for varied camping conditions, connecting the material to outdoor trailer use without requiring a separate material choice.

Skip it if you want a carrying bag listed with your blocks; ROBLOCK's RBTS578H-4 includes one with its four-block set.

This set suits trailer owners who want four stackable supports with a stated 6,000-pound capacity per block. Its listed dimensions and lack of a supplied carrying bag may affect storage and transport plans.

#9

9. RVMATE Leveling Blocks

Best for: Portable outdoor leveling set.

Why it ranks #9: This 12-piece stackable kit includes a carrying bag and two top caps, but the supplied specifications do not state a load capacity.

A carrying bag and two top caps make this RVMATE 12-piece set easy to organize between campsites while adding capped surfaces for use. The HDPE blocks are described as UV-resistant and waterproof, supporting outdoor use on uneven ground.

The set stacks to meet differing leveling needs, with each standard block measuring 8.5 inches square and 1.5 inches high; each top block has the same footprint and is 0.75 inch high. Two top caps add a defined upper surface, while the included bag keeps the pieces together during RV travel. RVMATE describes the blocks as heavy-duty and high-density, but the supplied specifications do not state a per-block load capacity.

Skip it if you require a published per-block capacity; VEVOR's CXFC02 is rated for 6,000 pounds per block.

RVMATE fits RV owners who want a portable, stackable set with two top caps and a carrying bag for outdoor trips. Its lack of a stated per-block capacity is a key selection boundary.

#10

10. OULEME Leveling Blocks

Best for: Custom-height modular leveling.

Why it ranks #10: The 12-piece interlocking kit offers adjustable stacking and a carrying bag, but the supplied specifications do not state a load capacity.

Ten interlocking leveling blocks plus two top blocks give the OULEME set a modular approach to RV support. Its pieces can be stacked to customize height, allowing owners to build up support in increments rather than rely on one fixed-height jack block.

The polypropylene blocks include anti-UV aging additives, and the product description also notes increased density and structural thickness; together, those material details are relevant to repeated outdoor use. Ten interlocking pieces and two top blocks let users configure stacks, while the carrying bag keeps the set organized during travel. The listed dimensions are 8.5 inches square for a standard block and 8.5 inches square for a top block, with respective stated heights of 1.5 and 0.7 inches.

Skip it if you need a stated 10,000-pound rating per block; Florety's R01V blocks carry that listed capacity.

Choose OULEME if adjustable stack height, interlocking pieces, and a carrying bag suit your travel routine. The supplied specifications do not give a per-block load rating, an important boundary for support selection.
