2x Front Lift Steel Torsion Keys2x Rear Coil Lift SpacersInstallation instructionsOur 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 Supreme rear coil spacers are precision engineered to lift and level your truck with ease. Our rear coil spacers are CNC machined from either solid 6061 T6 billet aluminum and anodized black or our special Delrin thermoplastic. We use Delrin and Billet specifically for our precision parts requiring high stiffness, low friction and excellent dimensional stability. Unlike polyurethane style spacers, our rear spacers will not dry up and will maintain a proper lift amount for the life of your vehicle.NOTES: 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.
