If you purchased a leveling kit for your 2011-2024+ Chevrolet Silverado OR GMC Sierra 2500HD / 3500HD tucks and your leveling kit did not include differential lowering spacers. You are now in luck, SuspenisonMAXX is now offering a solution to your problem. If you are suffering from extremely high CV axle angles and driveline vibrations, you need our differential drop kit. The front differential is lowered in two locations, the four large differential spacers lower the differential cross member where it mounts to the frame. The additional spacers lower the differential where it is attached to the cross member. The SuspenisonMAXX diff drop kit also includes skid plate spacers. These components are both available with our Stage 1 & Stage 2 packages. All differential lowering components are made in the USA from Billet Aluminum. Don't gamble on tearing up another set of CV boots, get the SuspensionMAXX diff drop kit today!
