The rear rearward shock absorber crossmember on certain Chevrolet Silverado and GMC Sierra 1500 series trucks can weaken and crack from rust. Fabricating a replacement crossmember is time-consuming, and the dealer solution—replacing the entire frame—is very expensive. This Dorman OE FIX shock crossmember is designed to save time and money, and is engineered to match the fit and function of the original equipment part. This repair requires grinding off existing weld points on the frame prior to welding on the new crossmember, which is painted in a corrosion-resistant finish for added durability.
