2x C.N.C. Machined Billet Front Lift SpacersInstallation InstructionsOur Pro-Billet Series 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.NOTES: Fits 2WD models only. Fits independent front suspension models only. An alignment is always recommended after altering the height of your vehicle.
