SUMHEN Fuel Tank Straps for Cadillac Chevy GMC — 2-Pack Black Rear-Mount, OEM Fit 578-237

The SUMHEN Fuel Tank Strap 578-237 is a pair of heavy-duty, corrosion-resistant steel straps designed to securely hold the fuel tank on select Cadillac, Chevrolet, and GMC SUVs and trucks.

If your vehicle shows signs of a worn or broken fuel tank strap — such as fuel tank sagging, rattling, or a noticeable fuel smell underneath — replacing the straps can restore safe support and prevent further underbody damage. SUMHEN supplies two black rear-mounted straps engineered to match OE fit and function for many model years of Cadillac Escalade, Chevrolet Avalanche, Suburban, Tahoe, and GMC Yukon vehicles.

Which vehicle models and years will these straps fit?

These SUMHEN straps cover a broad range of full-size GM SUVs and trucks from early 2000s through 2020 depending on the model. Compatibility includes multiple chassis variants like Escalade, Escalade ESV, Escalade EXT, Avalanche, Suburban (including 1500), Tahoe, Yukon, and Yukon XL.

• Cadillac Escalade: 2002–2020 (including ESV and EXT coverage where noted)
• Chevrolet Avalanche: selected years including 2002–2006 and 2007–2013 depending on submodel
• Chevrolet Suburban/Suburban 1500: 2000–2014 and 2015–2020 coverage for some models
• Chevrolet Tahoe: 2000–2014 (wide model year coverage)
• GMC Yukon/Yukon XL: 2000–2020 depending on model and year

What are the part numbers and physical specifications?

SUMHEN lists multiple reference numbers to help you cross-check OEM compatibility. Each kit contains two straps with measured widths and lengths to match factory mounting points and keep the tank stable under load.

How durable are these straps and how difficult is installation?

Manufactured from high-quality steel with corrosion-resistant coating, these straps are built to withstand road salt, grime, and seasonal exposure. Installation is straightforward for a mechanically inclined person; the straps use existing mounting points and common fasteners to replace worn or broken originals.

• Material: steel with anti-corrosion finish for long service life
• Designed to meet or closely match OEM form and fit
• Typical install: remove old straps, position tank, secure new straps using factory bolts
• Includes two straps so both mounting points are renewed at once

Will these straps resolve tank noise or leakage issues?

Replacing degraded straps often eliminates tank movement that causes noise and prevents additional wear to fuel lines and mounting hardware. While straps secure the tank, they do not address internal fuel system failures; inspect the tank and lines for damage or leaks and repair as needed.

• Stops sagging and excessive vibration when straps are the cause
• Prevents further chafing of lines and underbody components
• Not a repair for internal tank leaks — inspect tank condition before installation
