3PCS Front and Rear Fuel Tank Support Crossmembers & Rear Shock Mount Crossmember Kit, Fit for 2007–2014 Chevy Silverado 1500 & GMC Sierra 1500 Ext & Crew Cab Only, Frame Repair Beam
Ext & Crew Cab Fitment: Fit for 2007–2014 Chevrolet Silverado 1500 & GMC Sierra 1500 Extended & Crew Cab only. This 3PCS kit includes front & rear fuel tank support crossmembers and the rear upper shock mount crossmember for OE-position structural replacement
3PCS Structural Coverage: Rust typically spreads across multiple rear support points—not just one beam. This bundle rebuilds the front tank support, rear tank support, and upper shock mounting structure to restore frame integrity and reduce repeat repairs in rust belt trucks
Fixes Sag & Flex: Failed tank cross members can cause the fuel tank to sag, shift, and rattle, while shock-area rust can lead to rear-end looseness and clunking. Replacing all three restores proper support geometry and reinforces rear chassis stability for daily driving, hauling, and rough-road use
Weld-In Install Notes: Weld-on structural repair for permanent results: cut out the rusted sections, grind to clean metal, test-fit and clamp, then tack weld and fully weld all seams. Bed removal is not required in most installs (optional for extra workspace). Professional welding strongly recommended
OEM-Grade E-Coating: Built from heavy-duty structural steel and finished in gloss black E-coating for full-surface coverage and strong adhesion. Designed to resist road salt, moisture, and underbody debris better than basic paint or oil coatings for long-term durability
