2x Front Billet Lift Spacers2x Rear Poly Lift SpacersInstallation Instructions?Will not fit models with 3rd-row seat and tow package.Our Pro-Billet series full lifts are designed to accurately lift and level your truck for that more aggressive look over stock. The front Strut spacer is machined from 6061-T6 aircraft aluminum, then an anodized coating is applied to protect from rusting. Our rear spring spacers are injection molded from ultra-high density urethane and impregnated with special conditioners to never dry or rot. These spacers have proven time and again to provide customers with the fastest, most hassle-free install while maintaining your smooth factory ride quality. Unlike steel struts and blocks that are cut-out and welded together, our Pro-Billet kits are crafted from solid materials and will not bend or warp when under high-stress loads.NOTES: An alignment is always recommended after altering the height of your vehicle.
