GMC Duramax LML Transfer Case Brace by Wehrli – Chevy Orange (2011–2019). A purpose-built brace that ties your Allison transmission to the transfer case for added support under demanding use.

Developed and tested for high-power Duramax applications, this brace helps reduce driveline flex seen in off-roading, pulling, and drag racing. By spreading transfer case load into the transmission center section, it helps prevent cracked tail housings, leaks, and costly damage caused by vibrations from issues like a failing U-joint or driveshaft. The fabricated tubular steel support links the rear of the Allison to the transfer case for consistent reinforcement while retaining factory hardware and geometry.
