10 wide-footprint blocks at 40,000 lbs — more surface area for bigger rigs
Last reviewed: March 2026
Set of 10 interlocking polypropylene leveling blocks in the wider 4x2 size, rated at 40,000 lbs. The wider footprint provides more surface area under wider tires and larger jacks. Stacks up to 4.5 inches high with locking tabs.

Why this product
The wider 4x2 version doubles the surface area under each block. This matters when you are running wider tires or parking on softer ground. Same 40,000 lb rating, same interlocking design, but at 16 lbs for 10, they are noticeably heavier than the 2x2 set. The trade-off is worth it for rigs with wider tire profiles.
