Chevrolet Duramax Transfer Case Brace - Wehrli - Bengal Silver - 2001–2007. For LB7/LLY/LBZ trucks with the Allison, this brace adds reliable drivetrain support under hard use.

Developed and tested for high-horsepower use, the Wehrli Custom Fab brace links the transmission’s rear housing to the transfer case with a fabricated tubular steel support. By spreading load to the transmission center section, it helps reduce driveline flex that can lead to tail housing cracks, leaks, and costly repairs during off-roading, pulling, and drag racing. Finished in Bengal Silver single-stage powder coat, it installs with basic hand tools, reuses OEM fasteners, and does not require removing the transmission or transfer case.
