GMC Sierra Transfer Case Brace - Wehrli - Sparkle Bomber Orange - `01-`07. A purpose-built support brace for Duramax/Allison drivetrains that strengthens the transfer case interface under demanding use.

Developed and tested for 2001–2007 GM Duramax LB7/LLY/LBZ trucks, this fabricated tubular steel brace ties the Allison transmission’s rear housing to the transfer case, distributing load into the transmission center section. It helps reduce driveline flex seen in off-roading, pulling, and drag racing, and helps prevent cracked tail housings, leaks, and costly damage from vibrations caused by a damaged u-joint or driveshaft. Finished in Sparkle Bomber Orange.
