Product Information

Product Details
Part No. 999-978
Warranty Details (LIMITED LIFETIME REPLACEMENT)
The front crossmember supporting the fuel tank on certain standard cab Chevrolet Silverado and GMC Sierra 1500 Series trucks can rust, which can spread to the frame and ultimately cause a failed inspection. Fabricating a replacement crossmember is a labor-intensive job outside the comfort zone of most vehicle owners, and the dealer solution - replacing the entire frame - is very expensive. This Dorman OE FIX fuel tank 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 to prepare it for welding on the new crossmember, which is coated with a corrosion-resistant finish for durability. After installation, just spot-paint the weld points and heat-affected areas of the crossmember and frame as needed for added protection against the elements..

Product Features:
  • Ideal solution - this fuel tank crossmember is designed to save the expense of buying a whole new frame, or the time needed to fabricate a replacement for a rusted crossmember.
  • Application-specific - engineered to match the fit and function of the original front fuel tank crossmember on specified standard cab Chevrolet Silverado and GMC Sierra 1500 Series trucks
  • Welding required - the installation of this part requires grinding off existing weld points on the frame prior to welding on the new crossmember
  • Rugged construction - manufactured from high-strength quality steel and coated with a corrosion-resistant finish for added durability under the toughest conditions
