If you do a lot of hauling or towing, you understand how weight distribution can affect the performance of your truck. ReadyLIFT OE style rear block kits are designed to help distribute the weight of your cargo and improve the towing performance of your truck.

These block kits are designed to take the place of your factory blocks and are made out of cast iron, rather than some lightweight extrusion. The taller blocks will increase your rake, eliminate the dangers of stacked blocks, and work in perfect harmony with ReadyLIFT leveling kits.

All the necessary mounting hardware is included. Even new e-coated U-bolts come with each kit. The e-coating extends the life of your U-bolts and resists corrosion. The average time to install a rear block kit is about an hour to an hour and a half.

Make towing or hauling with your truck better and safer with a made in the USA ReadyLIFT OE style rear block kit, you won't regret it!
