Superlift rar block kits help distribute the weight of your cargo and improve the towing performance of your truck. They'll also give your rear a little lift to bring it back to the proper ride height.

These block kits are designed to take the place of your factory blocks and are made from cast iron for ultimate strength and longevity. The taller blocks will increase your rake, eliminate the dangers of stacked blocks, and they work well with suspension leveling kits.

Superlift includes all the necessary mounting hardware and new U-bolts will come with your new rear blocks. It won't take you much time at all to swap these in for your factory blocks. Make towing or hauling with your truck better and safer with Superlift rear block kits, they'll help make your truck "super"!

Looks to be a good product and the price is very good. Company was easy to deal with and the shipping was fast. I have not installed it yet but it looks pretty straight forward so I don't anticipate any problems.
