Supreme Pro Billet lift kits are engineered to accurately lift and level your truck for a truly customized ride. Each front and rear lift component is CNC machined from solid billet aluminum blocks. Each spacer then receives our special anodize coating protecting it against rust and corrosion. With its high strength and durability, this lift will never compress or warp even under the most extensive load. IMPORTANT: Rock Warrior Model will NOT fit 3" Front Spacer.
