This spacer kit is made to drop your differential and skid plate down so that your axles are not overextended causing them to prematurely wear and break. This is mainly built to accommodate the 3" lift kits, however this kit will work with the 2" and 2.5" kits. It's made from High Quality T6 Billet Aluminum that is Anodized as an extra layer of protection from oxidizing. Billet Aluminum lasts much longer than Rubber/Plastic Spacers.
Takes about an hour to install with only simple hand tools. This kit has a Lifetime Warranty for as long as you own your truck.
