To lift the rear, this system includes OEM quality cast iron 5.0" tall rear block that doesn't sacrifice ride quality.

The sub frame and other components are powder coated with a unique and improved Plascoat finish. The Plascoating on the components is a performance polymer alloy coating specifically designed to provide a long-lasting, tough coating for exterior applications. The Plascoat finish is especially resistant to stress cracking with improved abrasion and impact resistance as well as a great way to protect against adverse weather conditions, detergents, salt spray and other typical airborne pollutants.

NOTE: SRW (Single Rear Wheel) models may require custom U-Bolts to accommodate factory tow package. Will not fit DRW (Dual Rear Wheel) applications without custom U-bolts. Towing Capacity will be reduced with the installation of this kit.

NOTE: This kit is primarily designed to only be driven in 2WD at speed on public roads and that 4WD is only to be used off-road or in adverse slow speed conditions due to drive line vibrations at high speeds. Double cardan driveshaft may be required to help eliminate some of the high speed 4WD front driveline vibration when kits are 5-8" high.
