2x Front Lift Spacers2x Bump StopsInstallation instructionsIMPORTANT: Pro4X model will NOT fit 3" or 3.5" front spacersPlease check out our installation video:Our Pro-Billet series strut spacer lift kits are precision engineered from 6061-T6 aircraft aluminum, then anodized for a superior finish. Billet aluminum is a great material for use in suspension applications as it has an immensely high strength to weight ratio along with a superior level of corrosion resistance compared to many other metals on the market. Unlike steel kits that are cut-out and welded together, our Pro-Billet kits are machined from a solid piece and will not bend or warp under even the most stressful conditions. This kit also includes Energy Suspension upper control arm bump stops in order to maintain proper shock travelNOTES: An alignment is always recommended after altering the height of your vehicle.
