Product Description

The RustBuster RB7401L Center Frame Repair Section - Left/Driver Side - is engineered to restore structural integrity to Rust-prone frame rails on a range of full-size GM SUVs. Specifically designed for 2002-2013 Chevrolet Avalanche, 2000-2020 Chevrolet Suburban, 2000-2020 GMC Yukon XL, 2002-2013 Cadillac Escalade EXT, and 2003-2020 Cadillac Escalade ESV, this precision-cut frame piece caps the rail between the center support crossmember and fuel tank crossmember where corrosion and rust frequently weaken the boxed frame design. Built from heavy-duty 11 gauge steel and featuring perforated cut lines for easier alignment and body mount removal, the RB7401L delivers a robust OEM-style structural repair. 

This part ships with a protective oil coating to resist oxidation during storage and includes a lower trailing arm mount with Class 10.9 hardware for secure installation. Welding is required to complete the repair, making it suitable for experienced DIY installers or professional frame repair technicians. Backed by RustBuster's lifetime warranty, RB7401L helps extend frame life and reinforce critical support areas on some of GM's most durable SUVs.
