Trailer Jack Blocks, 2-Pack, 6-Inch, 6000 lb Capacity

Trailer jack blocks add a wider, higher base to keep your RV steady on soft or uneven ground. Each 6-inch heavy-duty leveling block supports up to 6,000 lb to reduce sinking, rocking, and jack twist on gravel, grass, sand, or snow. The recessed top fits common round or square jack legs and many trailer support wheels, while reinforced feet and side holes help you position and remove them fast at every stop.

• Delivers stable leveling by expanding jack footprint to reduce sink-in on soft terrain.


• Fits round or square metal jack legs plus many trailer support wheels and insertable legs.


• Supports up to 6,000 lb (2.7 tons) per block for travel trailers, 5th wheels, and Class A/C RVs.


• Grips surfaces with durable PP construction to help prevent slipping, shifting, or pop-out.


• Includes 2 multi-purpose blocks that can also serve as a step, seat, or stand in camp.

Built for quick setup and confident parking, these RV leveling blocks bring extra height and contact area where thin pads fall short—especially on rutted campsites, dips, and loose gravel. The recessed top keeps the jack centered, while the triangular reinforced feet spread load for steadier support. Keep a pair in your camper accessories kit for weekend getaways or long-haul trips. Grab yours today and level up with less hassle at every stop.
