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". Our Pro-Billet Series rear lift kits are precision engineered to lift and level your truck. The rear lift blocks are machined from 6061-T6 aircraft aluminum, then an anodized coating is applied to protect from rusting. Unlike steel blocks that are cut-out and welded together, our Pro-Billet kits are machined as a solid piece and will not bend or warp when under high stress loads. We complete this kit with high grade hardware and extended OEM spec zinc plated U-bolts. Our Supreme Suspension extended length shock absorbers have been specially designed and custom valved to work in conjunction with our lift kits as well as other lift kits from different manufacturers. The custom valving in our shocks will help maintain proper vehicle handling dynamics with the higher than factory center of gravity, while still maintaining a factory like ride quality. The extended length of our shocks over factory lengths provides you with the ability to use your suspension?s new fuller range of motion while eliminating binding and shock limiting. Our differential shim kit has been specially engineered to help correct the pinion angle of your vehicle back to factory specifications. An incorrect pinion angle can cause driveline vibrations when driving at speeds, and will severely shorten the lifespan of the differential pinion bearing. CNC machined from billet aircraft aluminum, these are designed to never compress or change angle. They?re also manufactured with provisions for center axle alignment pins, and utilize raised grip steps to help keep all components secured in place.
NOTES: Fits 2500 models only. 8-lug 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.
