1988-1999 GMC K3500 Rear Suspension Lift Kit & U bolts 4WD
- 2x Rear Lift Blocks
- 4x Zinc Plated U-Bolts
- Installation instructions
Our 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 zinc plated U-bolts.
NOTES: An alignment is always recommended after altering the height of your vehicle.
