Performance Accessories designed a 2" leveling kit for Chevy/GM pickups and SUV's that corrects the front-to-rear stance of the vehicle. This coil spring leveling kit, features machined billet aluminum spacers that sit on the coil spring mount, and the top strut mount plate. System comes with everything including heavy-duty hardware and thread locker along with detailed instructions. Dividing the lift between the coil spring and the top of the strut, eliminates excessive coil spring pre-load, and limits the overall length of the strut, resulting in a smooth ride while maintaining proper suspension geometry to prevent premature component wear.
