The GMC Sierra Transfer Case Brace - Wehrli - WCFab Grey - 07.5–10 reinforces LMM Duramax/Allison drivetrains by tying the transfer case to the transmission tail housing.

Developed and tested for high-horsepower use, it reduces driveline flex common in off-roading, pulling, and drag racing. By linking the Allison rear housing to the transfer case, it helps prevent tail-housing cracks, leaks, and repairs from vibrations caused by worn U-joints or driveshaft issues. Durable single-stage WCFab Grey finish. Installs with basic tools using OEM fasteners; no transmission or transfer case removal.
