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.
Also included in this Do-It-Yourself kit which includes our extreme duty torsion key installation tool. Don’t spend hours trying to locate, borrow, or rent a generic “compressor” tool just to find out it won’t work for your truck. Our torsion key tools are designed to ensure the fastest, easiest, and safest installation possible.
NOTES: Front torsion keys are adjustable anywhere from 1" to 3". An alignment is recommended when changing the height of your vehicle
