GMC Sierra 2500 Transfer Case Brace by Wehrli, Brizzle Blue, 2001–2007. A proven support that ties your Allison transmission to the transfer case for added strength under heavy use.

Developed and tested on high-horsepower Duramax builds, this tubular-steel brace addresses driveline flex seen in off-roading, pulling, and drag racing. By spreading transfer case load into the transmission center section, it helps reduce the chance of cracked tail housings, fluid leaks, and costly repairs caused by vibrations from a damaged u-joint or driveshaft. Installation is straightforward with basic hand tools, requires no removal of the transmission or transfer case, and reuses OEM fasteners. Finished in Brizzle Blue powder coat.
