Supreme Suspensions has the best products with the best prices. We believe in Safety and Standards in both machining and manufacturing. Unlike our competitors who offer you low prices for inferior products, we build products that lift and level your vehicle without compromise. Cutting corners is awesome when driving your truck, but not when manufacturing, buy right, choose Supreme.

This Differential Drop is highly recommended for 4WD Sierra pickup trucks with 6-lug axle configurations. This kit will lower your front differential and reduce the excess wear on CV joints and axles caused from lifting the front of your truck. This is perfect for trucks with lift kits from our Pro-Billet series, as well as with pre-existing coil spring spacers already installed on your truck. Supreme Suspensions Pro-Billet Series spacers are precision engineered from T6 Aircraft Billet, then anodized for a superior finish. Unlike steel kits that are cut-out and welded together, our Pro-Billet products are built from a solid piece and will not bend or warp when stress is applied. All Supreme Suspensions' products are developed and rigorously tested by in-house ASE certified specialists, in conjunction with sponsored, professional racers as well as dealerships across the US.
