Wehrli Custom Fab GMC Duramax Transfer Case Brace, Semi-Gloss Black (2001–2007). This brace ties the Allison transmission rear housing to the transfer case for added support.

Developed and tested on high-power Duramax builds, it helps reduce driveline flex in off-road, pulling, and drag use. By spreading transfer case load into the transmission center section, it reinforces the tail housing and helps curb vibration-related issues such as cracked housings, leaks, and costly repairs. Fabricated from tubular steel, it installs with basic hand tools, needs no drivetrain removal, and reuses OEM fasteners.
