These new Rear Coil Spring Spacer Kits include a pair of CNC-machined 6061-T6 aircraft-grade billet aluminum rear coil spring spacers that easily install under the OEM rear coil spring. These ReadyLift rear spacers are ideal for adding a slight rake to a vehicle for towing or hauling, or if you have installed a leveling kit to fit larger wheels and tires in the front, and want to bring the back end up for a raked stance. ReadyLift Rear Coil Spring Spacers are designed to work with your ReadyLift Suspension Leveling Kit or by themselves. Like all ReadyLift products these block kits come with our Lifetime Warranty. Installation time is approximately 1 plus hours. Do not settle for cheap plastic or urethane rear spacers that will split over time. Demand the best quality suspension product for your expensive SUV or SUT. Demand ReadyLift CNC-machined billet aluminum rear coil spring spacers. Your vehicle deserves the best.
