Our Max-Torsion Key Lift Kits are engineered with twice the strength of the factory system and precision indexed to lift your truck without sacrificing ride quality. This kit replaces your factory torsion key and is precision indexed to lift and level your front end any amount from 1" to 3".
Supreme Suspensions is proud to carry Pro Comp's ES9000 shock series to replace your factory shocks when you install your lift kit. These are top of the line Nitrogen charged shocks that are engineered with performance in mind. They are a twin-tube construction with a hardened piston rod vs. the factory single tube construction and contain a 10-stage velocity sensitive valving which provides amazing comfort AND toughness.
NOTES: Fits 6 -lug 4WD models only. Front torsion keys are adjustable anywhere from 1" to 3". A torsion bar puller (can be rented at most chain auto stores), or 5 ton gear puller is required for install. We also offer this tool with our kits in our other listings. An alignment is always recommended after altering the height of your vehicle.
