Fits 8-Lug models ONLY.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 U-bolts. We've specially engineered our shock extenders to provide our customers with the option to reuse the vehicle?s factory shock absorbers to avoid the need to purchase expensive aftermarket extended shocks. Our extenders are laser cut from high-carbon steel to provide precision fitment and extreme strength at your shock mounting point. Coated with a long lasting, durable finish to prevent corrosion, and completed with high-strength hardware to keep everything secure. 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 4WD HD 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.
