Who It's For

This kit is aimed at DIY mechanics and professional technicians working on late-model GMT800 and early GM pickup frames who need to replace worn rear hanger brackets and shackles. It suits owners restoring truck suspension, replacing damaged mounts after rust or collision, or refreshing components to improve ride comfort and spring longevity.

Those who should look elsewhere include drivers with models outside the 1999-2013 Silverado/Sierra 1500 range or anyone requiring front spring hangers or unrelated suspension components. Also, if a vehicle has significant frame damage, a kit replacement alone will not address structural issues.
