2x Front Billet Lift SpacersInstallation instructionsOur Pro-Billet series strut spacer lift kit for the Ford Expedition is precision engineered from 6061-T6 aircraft aluminum, then anodized blue 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.NOTES: Does not fit Platinum trim or Models equipped with CCD independent or auto-ride suspensions. An alignment is always recommended after altering the height of your vehicle.
