This is a TRUE 8 inch Lift Kit for the Silverado and Sierra. It was designed and engineered to be an 8 inch lift from its conception unlike some companies that use their 6 inch lift components with a taller strut spacer to achieve 8 inches of lift. The steering knuckles, crossmembers and differential drops provide all the proper geometry correction for the true 8 inches of lift.
Using OE data files allows us to design lift kits that mimic the original factory designed components. This aids in installment and compatibility. It also allows our engineers to design a kit that once installed not only retains your truck truck's excellent ride and handling characteristics, but one that is also compatible with GM's Stabilitrac anti-skid system.
Nothing is left unattended with this 8" lift kit. The brake lines and front sway bar are relocated to make sure there is no binding through the cycle of the suspension.
The differential is dropped for the 8" lift and does not require you to cut the passenger's side front mount off the axle tube. The differential skid plate not only protects the diff housing, it also adds rigidity to the crossmembers.
The rear includes a set of fabricated lift blocks that locks in the axle ubolts though the blocks upper and lower plate giving you the strongest set of blocks on the market today. The block also has ubolts that captures the leaf pack to help counter axle wrap.
