The Dorman truck bed floor support / crossmember repair kit, part number 999-995, lets you repair a rust-damaged truck bed by replacing only the failed floor supports rather than the whole bed, helping keep repair costs down. It fits many vehicles, among them the 2007-2014 Chevrolet Silverado 1500, 2011 GMC Sierra 1500 and 2007-2014 Chevrolet Silverado 2500 HD. See the Buyer's Guide tab for the full list.
When a truck bed crossmember rusted, replacing the entire bed used to be the only option. This Dorman OE FIX kit changes that by addressing just the damaged supports. The part is listed under two names, truck bed floor support and truck bed crossmember repair kit. The listed applications use one kit.
- Saves money: replace only the damaged crossmembers instead of the complete bed.
- What's in the kit: 4 bed crossmembers painted in weldable primer, plus 8 M12 bolts and 8 M6 bolts for installation.
- Application specific: made as a direct-fit replacement for the listed applications.
- Quality engineering: designed in the United States and backed by decades of automotive aftermarket experience.
Signs your floor supports may need replacing include visible rust, flaking or perforation on the crossmembers beneath the bed, or a bed floor that sags or flexes under load. Inspect the bed structure to confirm which supports have failed before starting the repair.
