Best Fifth Wheel Blocks For Dump Trailer

#1 · Best Overall

1. Florety Trailer Jack Blocks

• Load Capacity: 10000 lb
• Material: Polypropylene
• Compatible with Vehicle Type: RV

Best for: Large-foot jack support.

Why it ranks #1: The four-pack is specified for fifth wheels and trailers, with a 10,000-pound rating per block and a broad 12.5-inch square base.

An 8-inch height and broad 12.5-inch square base give the Florety blocks a substantial platform for trailer jack feet. Each block is rated for 10,000 pounds of jack support, while the large top can support the entire foot of a camper’s leveling jack, helping spread contact across the pad.

The 12.5-by-12.5-inch base and rounded, larger-footprint design provide a broad foundation, and the side notches near the top allow blocks to be handled together. A multi-functional top profile accommodates round and square jack types, so these pads can serve different support points around a fifth wheel or travel trailer. Polypropylene construction replaces the wooden blocks they are compared with in the supplied description; the 8-inch height is a fixed addition beneath the jack.

Skip it if you need a lower-profile pad; the 8-inch height is fixed and may add more lift than your setup calls for.

Choose Florety if your fifth wheel or camper needs a tall, broad platform beneath round or square jacks. The 10,000-pound rating is per block; account for the fixed 8-inch height when positioning the jack.

#2 · Highest Capacity

2. KJE Trailer Jack Blocks

• Load Capacity: 40000 lb
• Material: PP
• Compatible with Vehicle Type: RV, Trailer, motorhome

Best for: Weather-resistant travel set.

Why it ranks #2: Four trailer blocks and a carry bag suit a multi-jack setup, while the listed 40,000-pound capacity is the highest stated rating here.

Anti-UV additives in KJE’s industrial-grade PP blocks address sun exposure during outdoor trailer use, while the integrated drainage hole lets water and mud escape. The 6-inch height gives jacks a fixed lift, and the included bag keeps the four blocks together for transport between stops.

KJE lists a 40,000-pound load capacity and compatibility with fifth wheels, travel trailers, posts, feet, and round or square tongue jacks. That broad stated range makes the four-block set applicable across several support points, while the drainage hole helps limit water and mud accumulation around the blocks. Industrial-grade PP with anti-UV additives is specified to resist dirt, grime, oil, and sun damage. The 6-inch height is a set dimension rather than an adjustable leveling ramp.

Skip it if you need to build up height in small increments; each KJE block is a fixed 6 inches rather than a stackable leveling ramp.

KJE suits RV owners wanting four 6-inch jack blocks with a carrying bag and drainage for outdoor stops. Its stated 40,000-pound capacity and listed jack compatibility are useful, but the fixed block height limits fine height adjustment.

#3 · Weather-Resistant Pick

3. KIKIRV Trailer Jack Block

• Load Capacity: 4E+4 lb
• Material: Polymer
• Compatible with Vehicle Type: RV, Trailer, Truck

Best for: High-capacity jack pad.

Why it ranks #3: Its polymer block is listed at 40,000 pounds and is described as UV-, water-, heat-, and weather-resistant for outdoor trailer use.

KIKIRV rates each 6-inch trailer jack block for up to 40,000 pounds, giving heavy RV and trailer owners a high-capacity pad at a fixed height. Its polymer material is specified to resist UV, oil, water, heat, stains, and weather, supporting outdoor use across varied conditions.

The 6-inch height provides a consistent lift beneath tongue jacks, wheel jacks, scissor stabilizers, and fifth-wheel hydraulic jacks. That listed compatibility lets the same block serve multiple kinds of support point, while the polymer’s stated resistance to water, heat, oil, stains, UV, and weather suits outdoor exposure. The 40,000-pound capacity is specified per pad, so it applies to each block rather than describing an adjustable system. Its fixed height is a practical boundary when a setup needs a different amount of lift.

Skip it if you need to raise a jack in smaller increments; KIKIRV’s block is fixed at 6 inches rather than a stackable ramp.

KIKIRV suits owners of RVs, trailers, or trucks who want a weather-resistant, 6-inch pad for several listed jack types. Its per-pad capacity is substantial, but the fixed height may not match every support setup.

#4 · Made in USA

4. EKON OX BLOX

• Load Capacity: 10000 lbs
• Material: Heavy Duty Recycled Plastic
• Compatible with Vehicle Type: Trailer

Best for: Rough-ground jack support.

Why it ranks #4: This four-pack of recycled-plastic blocks is rated at 10,000 pounds and is specified for tongue jacks, posts, feet, and stabilizers.

OX BLOX are specified to remain stable on grass, gravel, dirt, and asphalt, giving trailer owners more surface options for jack support. The four-pack supports up to 10,000 pounds and fits round or square tongue, post, foot, and scissor jacks, making it a versatile set for varied trailer support points.

The heavy-duty recycled-plastic construction is described as UV-resistant and able to withstand extreme temperatures, which supports outdoor use across changing conditions. A capacity of up to 10,000 pounds gives the blocks a stated load boundary, while compatibility with tongue, post, foot, and scissor jacks lets one set serve multiple types of support point. The verified surface list includes grass, gravel, dirt, and asphalt. The four blocks weigh 8.9 pounds together, a consideration when packing them for travel.

Skip it if you need a lighter four-block set to carry; the OX BLOX set weighs 8.9 pounds, while LEIDGG’s listed kit includes handles for carrying.

Pick EKON OX BLOX for a trailer owner who needs jack support on several listed ground surfaces and uses different jack styles. Its 10,000-pound rating and 8.9-pound set weight are the key limits to weigh.

#5 · Flexible Capacity

5. BULLKE Trailer Jack Blocks

• Load Capacity: 10000 lbs
• Material: Plastic
• Compatible with Vehicle Type: RV, Trailer, Camper

Best for: Firm-ground jack support.

Why it ranks #5: The four-pack is rated up to 10,000 pounds without Flex Pads and up to 18,000 pounds with them, subject to stated ground and placement conditions.

BULLKE’s blocks have a clear surface-use boundary: install them only on firm, level ground. On that base, the four-pack is rated up to 10,000 pounds without Flex Pads, or up to 18,000 pounds with BULLKE Flex Pads when the jack foot is centered, making setup conditions central to the load rating.

The stated compatibility covers RVs, campers, trailers, fifth wheels, tongue jacks, post jacks, foot jacks, stabilizer jacks, and scissor jacks, so the set can serve many support locations. The capacity changes with the specified Flex Pad condition: up to 10,000 pounds without them and up to 18,000 pounds with them, used properly on firm, level ground and with the foot centered. That makes surface preparation and centering part of the setup, not optional details. The blocks are made from plastic and weigh four pounds.

Skip it if you must place blocks on gravel, rocks, or uneven ground; BULLKE expressly restricts use to firm, level ground.

BULLKE fits owners who can set up on firm, level ground and want blocks for several jack styles. Follow the stated centered-foot condition and Flex Pad distinction when applying its two different capacity ratings.

6. EKON OX BLOX MAXX

• Load Capacity: 10000 lb
• Material: Heavy Duty Recycled Plastic
• Compatible with Vehicle Type: Trailer

Best for: Large-foot fifth-wheel support.

Why it ranks #6: This 10,000-pound jack block is sized for large feet, with the listing identifying 9-inch round jack feet as a fit target.

Corner ridges help keep a jack foot secure on the OX BLOX MAXX, which measures 10.5 inches square and 4.5 inches high. Its verified fit includes 9-inch large round jack feet found on many fifth wheels, making foot size a useful starting point when choosing this block.

The corner ridges and large square footprint address foot stability, while the 10,000-pound rating supplies a stated capacity for trailer, RV, fifth-wheel, and stabilizer use. Heavy-duty recycled plastic is specified as UV-resistant, and the verified surface list includes grass, gravel, dirt, and asphalt. At 4.5 inches tall, the block provides a fixed platform rather than a variable-height ramp. Checking the jack-foot dimensions against the listed 9-inch large-round-foot fit helps buyers assess whether its footprint suits their equipment.

Skip it if you need adjustable height from a ramp; the MAXX is a fixed 4.5-inch block, while RVMATE’s blocks stack for height changes.

OX BLOX MAXX suits fifth-wheel owners with a large round jack foot who want ridged support and a fixed 4.5-inch platform. Its listed 9-inch fit and 10,000-pound rating define the key boundaries.

7. CircleRoad Trailer Jack Blocks

• Load Capacity: 10000 lb
• Material: Plastic
• Compatible with Vehicle Type: Tractor, Trailer, Truck

Best for: Four-pack broad-base pads.

Why it ranks #7: The four-pack is listed for trailers and has a 10,000-pound capacity, with 11.5-by-11.5-by-4-inch dimensions for fit checks.

CircleRoad supplies four trailer jack blocks with an 11.5-inch square footprint and a 4-inch height, giving each support point a broad, fixed platform. The listed load capacity is 10,000 pounds, and the product title identifies the pads as UV resistant for outdoor trailer use.

The 11.5-by-11.5-inch footprint provides a defined base beneath a jack, while the 4-inch height adds a consistent amount of support rather than allowing ramp-style adjustment. CircleRoad lists a 10,000-pound load capacity and compatibility with tractors, trailers, and trucks, so the blocks are not limited in the specifications to RVs alone. Their material is plastic, and the product title specifies UV resistance. The four-pack format supplies multiple pads for a setup that uses several support points.

Skip it if you need adjustable height rather than a fixed pad; CircleRoad’s blocks are 4 inches tall, while RVMATE’s blocks stack in stages.

CircleRoad suits trailer, truck, or tractor owners seeking four broad, 4-inch jack pads with a stated 10,000-pound capacity. The fixed height is the main fit consideration if your setup requires more precise leveling.

#8

8. RVMATE Leveling Blocks

Best for: Stackable leveling set.

Why it ranks #8: These stackable HDPE blocks include two top caps and a carrying bag, but their leveling-block design is less directly suited to supporting a jack.

RVMATE’s 8.5-inch-square blocks stack to the height you need, giving trailer owners a way to adjust support on uneven ground. The 12-piece set includes two top caps for added stability in use, while its carrying bag helps keep the blocks organized during RV travel.

Each main block measures 8.5 by 8.5 inches and 1.5 inches high, while each top block measures 8.5 inches square and 0.75 inch high. Those separate heights allow the stack to be built up in stages rather than relying on a single fixed-height pad. The two top caps add stability at the top of the stack, and the supplied bag provides a place to organize the pieces between stops. HDPE construction is specified as UV-resistant and waterproof for outdoor use.

Skip it if you want a single jack pad with a stated load rating; RVMATE’s listing gives stackable dimensions but no load-capacity figure.

RVMATE fits RV owners leveling on uneven ground who want stackable pieces, top caps, and a travel bag. Its listed dimensions support staged height adjustment, but the supplied specifications do not state a load capacity.

9. LEIDGG RV Leveling Blocks

• Load Capacity: 35000 lb
• Material: Polypropylene (PP)

Best for: Handled leveling kit.

Why it ranks #9: The 35,000-pound listing and included ramps, chocks, and mats target wheel leveling rather than a dedicated jack-foot support block.

Integrated handles let LEIDGG’s leveling blocks be carried, placed, and removed without gripping the block body, while the kit combines ramps, chocks, and rubber mats. With a 35,000-pound load capacity, it targets large RVs, travel trailers, fifth wheels, and trucks that need a complete leveling workflow.

The listed sequence is straightforward: place the non-slip mat, adjust the camper on the leveler to the desired height, then secure it with the chock. That combination of two curved ramps, two chocks, and two rubber mats provides the parts for the stated leveling process, and the integrated handles help with positioning and removal. High-strength PP construction is specified, and the set’s 35,000-pound capacity is intended for large RVs, trailers, fifth wheels, and trucks. Its dimensions are 13.2 by 6.1 by 4.3 inches.

Skip it if you want only a single jack pad and no ramp, chock, or mat setup; this LEIDGG kit includes several leveling components.

Choose LEIDGG if you want a handled leveling kit for a large RV, fifth wheel, travel trailer, or truck, with ramps, mats, and chocks. Its listed workflow involves multiple pieces and a 35,000-pound capacity.
