GMC Sierra 2500HD Transfer Case Brace - Wehrli - WCF - Flat Black - 01-07. A purpose-built brace that ties the rear Allison housing to the transfer case to add strength and control driveline movement.

Developed and tested for high-horsepower 2001-2007 Duramax LB7/LLY/LBZ applications, this fabricated tubular steel support spreads transfer case loads into the transmission center section, reducing flex that can lead to cracked tail housings, leaks, and costly repairs. Ideal for hard use such as off-roading, pulling, and drag racing, it installs with basic hand tools using existing OEM fasteners; no transmission or transfer case removal required. Finished in durable flat black single-stage powder coat.
