Dorman 999-978 Fuel Tank Crossmember

Detailed Description

The Dorman 999-978 fuel tank crossmember addresses a common rust issue on the front crossmember supporting the fuel tank in certain standard cab Chevrolet Silverado and GMC Sierra trucks. When the original support corrodes, it can spread to the frame and lead to inspection failure. This replacement is engineered to restore the original support location and function without the expense of a full frame replacement. It is a specific-fit, weld-on repair finished in black for corrosion resistance and built for direct service on the affected truck platform. This part cross-references OE numbers such as 15928192 and 22832052 for the same application.

What It Helps Repair

  • Rust damage at the fuel tank crossmember
  • Frame corrosion spreading from the original support area
  • Inspection failure caused by weakened frame structure
  • Costly frame replacement on Chevrolet Silverado and GMC Sierra trucks
  • Time-consuming fabrication of a custom replacement crossmember

Installation Notes

Installation requires grinding off the existing weld points on the frame before welding in the new crossmember. After welding, spot-paint the weld areas and any heat-affected sections of the crossmember and frame as needed for additional protection. This is a weld-on repair and does not require drilling.
