2x Front Lift Steel Torsion Keys2x Rear Lift Blocks4x Premium Electrostatic Powder Coated2x Pinion Alignment ShimsInstallation instructionsIMPORTANT: Does not fit Mega Cab Models.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 New 2019 Lightweight Steel Blocks for Rear Lifts constructed from 1-Piece CNC Formed Steel Frame. For maximum strength and stability, we designed our blocks with a 1/4" Thick CNC Plasma Cut Center Support Structure and Reinforced, Supported Center Pin. We fabricated our Blocks with Built-In Tapper to Optimize Pinion Angles and preserve stock ride quality. We complete this kit with high grade hardware and extended OEM spec U-bolts. 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 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.
