Mountainpeak Rear Fuel Tank Crossmember for 2007-2014 Chevy Silverado 1500 & GMC Sierra 1500

Premium fit for your truck

Mountainpeak Rear Fuel Tank Crossmember is designed to replace the rear crossmember for 2007–2014 Chevy Silverado 1500 and GMC Sierra 1500. The result is a sturdy rear-frame reference that supports daily driving and restoration projects with confidence.

Why this crossmember stands out

• Precise fit for your truck: matches the original geometry to help restore proper rear-frame alignment.
• E-coating protection inside and out: constant moisture and road salt exposure are met with an electrophoretic coating that resists corrosion over time.
• Heavy quality material: CNC-cut premium steel provides consistent strength under fuel tank load and long-term durability.

Durability you can feel

• Long service life: robust construction is designed to hold up under daily use and repair cycles.
• Reliable support for the fuel system: engineered to maintain tank stability and mounting integrity.

Easy installation for busy projects

• No bed removal needed: install with the gas tank removed, then weld in place and reinstall components.
• Clear steps: remove the old crossmember, swap in the replacement, and secure with welds and new shocks if needed.

Fitment and use cases

This crossmember sits just in front of the rear axle, replacing the original part to help rebuild the frame structure during repair or restoration. It’s a practical upgrade for Silverado and Sierra models in the specified years.
