2x Differential Drop SpacersInstallation HardwareInstallation instructionsWe are proud to offer you our brand new Differential Drop Kit, precision CNC machined from American High Grade Polyurethane made in Shelton, Connecticut. CNC Machined Billet Aluminum inserts are embedded deep in the polyurethane to further ensure the strength of our diff drop spacers, providing superior resistance for a lifetime of dependability under even the most extreme riding conditions. Supreme Suspension's Diff Drop Kit is suitable for vehicles with 2-4" lift kits from our Pro-Billet series, as well as with pre-existing coil spring spacers already installed. This set of differential drop spacers is designed to lower your front differential and reduce the excess wear on CV joints and axles caused from lifting the front of your truck.NOTES:Fits 6-Lug, 4WD models only.
