      If you do a lot of hauling or towing, you understand how weight distribution can affect the performance of your truck. A rear block kit is designed to help distribute the weight of your cargo, improve the towing performance of your truck, and give you a little lift in the rear.

      Zone Off-Road rear block kits are designed to take the place of your factory blocks and are made out of cast iron right here in the good ol' USA. Increasing your block height will increase your rake, eliminate the dangers of stacked blocks, and they also work great with leveling kits.

      There is no mounting hardware included. Zone does offer new U-bolts, which are sold separately. 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 Zone Off-Road rear block kit, you won't regret it!

      I am 6'4" and the 3" lift on my 2002 Silverado just didn't cut it. Once I installed the 5" blocks and adjusted the front torsion bars I now have the right height and 1/2" rake I was looking for. You will need to get longer rear shocks and recommend welding a few bolts together to raise the brake line on the rear axle. Other than that the are very straight forward, positioning marked properly and coated well.
