1988-1999 GMC K3500 Rear Suspension Lift Kit & U bolts 4WD 1.5"

2x Rear Lift Blocks4x Premium Electrostatic Powder Coated U-BoltsInstallation instructionsOur 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 U-bolts.NOTES: An alignment is always recommended after altering the height of your vehicle.
