Our Pro-Billet series strut spacer lift kits are precision engineered from 6061-T6 aircraft aluminum, then anodized for a superior finish. Billet aluminum is a great material for use in suspension applications as it has an immensely high strength to weight ratio along with a superior level of corrosion resistance compared to many other metals on the market. The rear lift blocks are machined from 6061-T6 aircraft aluminum, then an anodized coating is applied to protect from rusting. 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. 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.

Supreme Suspensions is proud to carry ProComp's upgraded strut series to replace your factory shocks when you install your lift kit. These are top of the line Nitrogen charged struts that are engineered with performance in mind. They are a twin-tube construction with a hardened piston rod vs. the factory single tube construction and contain a 10-stage velocity sensitive valving which provides amazing comfort AND toughness. We guarantee you will notice the difference in performance over your factory struts.

NOTES: Fits 6-lug models only. An alignment is always recommended after altering the height of your vehicle.
