If you do a lot of hauling or towing, you understand how weight distribution can affect the performance of your truck. Rugged Off-Road 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 any leveling kits.

All the necessary mounting hardware is included. Even new U-bolts come with each kit. The finish on the blocks and U-bolts will extends their life and resist 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 new rear block kit from Rugged Off-Road, you won't regret it!

Our suspension products are engineered and built to provide years of trouble-free service. Rugged Off-Road backs its outstanding suspension products with an exceptional 5 year - 60,000 mile RuggedShield Powertrain Warranty. The RuggedShield Warranty is FREE with the purchase and professional installation of any Rugged Off-Road suspension product. This exclusive RuggedShield Powertrain Warranty program covers all major powertrain parts so customers can have the peace of mind that their vehicle is covered in the event of a failure related to suspension modifications.

RuggedShield covers the vehicle if a properly-installed Rugged Off-Road suspension product causes damage to the powertrain or specified engine components on the vehicle in question.
