Shadow Series Rear Shocks. SuperLift includes nitrogen-charged, twin-tube Shadow Series Shocks in this kit for improved handling. Featuring a hardened chrome piston rod, these Shadow Series Shocks have a 2-inch diameter, straight-wall shock body that allows for improved heat dissipation. These Shocks are completed in durable, gunmetal grey finish for impressive good looks and long lasting durability.
Lifted Steering Knuckles. SuperLift includes a set of heavy duty replacement steering knuckles in their 6-inch Suspension Lift Kit. These lifted steering knuckles are CNC-machined from iron for precision and superior strength. The knuckles are designed to increase ride height while keeping all components at the optimum angles for a factory-like ride.
Fabricated Rear Lift Blocks. The Rear Lift Blocks included in this SuperLift Kit have been fabricated from high grade steel for superior strength and extra rigidity. This fabricated block replaces the stock block and allows for proper pinion and axle angle all while reducing axle wrap.
Bolt-on Installation. SuperLift engineered their Lift Kit to be installed with no welding needed, making it a bolt-on kit. However, it should be noted that professional installation is recommended. With all the necessary hardware included, this Lift kit can be installed in about 8 hours time. Please note that an alignment is highly recommended after installation.
