JY PERFORMANCE Rear Fuel Tank Support Crossmember for 2007–2014 Silverado/Sierra 1500 — Heavy-Duty Steel, Black Finish

JY PERFORMANCE Rear Fuel Tank Support Crossmember is a heavy-duty steel replacement that secures the rear fuel tank and passenger-side upper shock mount on 2007–2014 Chevy Silverado 1500 and GMC Sierra 1500 models.

This crossmember is engineered as a direct-fit replacement for the original part located in front of the rear axle. Finished in black paint, it restores structural support for the rear of the fuel tank and the passenger-side upper shock mount after removal of a damaged or corroded OEM crossmember. The design focuses on strength and simplicity so technicians and DIY installers can weld it into place and return the truck to safe operation.

How does this crossmember restore tank stability?

Replacing a rusted or bent crossmember prevents tank movement that can lead to fuel line strain or rattles. This unit reestablishes the factory mounting geometry for the rear of the fuel tank, holding it firmly under acceleration, braking and while cornering.

• Made from heavy-duty steel for load-bearing support
• Supports rear of fuel tank and passenger-side upper shock mount
• Restores original mounting points and alignment
• Black painted finish resists corrosion until final welds are sealed

Will it fit my 2007–2014 Silverado or Sierra?

This crossmember is listed specifically for 2007–2014 Chevy Silverado 1500 and GMC Sierra 1500 pickup trucks. It replaces the original crossmember located just in front of the rear axle and matches the carrier and shock mounting locations of those model years.

• Direct compatibility with 2007–2014 Silverado 1500 and Sierra 1500
• Designed for the factory rear axle and tank geometry
• Verify part fits your specific trim and bed configuration before ordering

How difficult is installation and what tools are needed?

Installation requires removal of the fuel tank and the old crossmember, cutting away the rusted OEM piece, and welding the new crossmember into place. It's straightforward for experienced mechanics or weld-capable DIYers but should be done with proper safety procedures and fuel system precautions.

• Fuel tank removal hardware and jack or lift
• Cutting tools to remove the old crossmember
• Welding equipment for secure attachment
• Torque tools to reinstall tank straps and shocks

What materials and durability can I expect?

The crossmember is fabricated from heavy-duty steel and completed with a black painted finish to provide resistance against road corrosion and extend service life. It is built to withstand the loads imposed by a full tank and the rear suspension mounting points.

• Heavy-gauge steel construction for strength
• Black paint coating for initial corrosion resistance
• Engineered to carry tank loads and shock mount loads
