GMC Sierra Transfer Case Brace by Wehrli, Fine Texture Black, 01-07. For 2001-2007 Duramax LB7/LLY/LBZ with Allison, it reinforces the transmission-to-transfer case interface.

Developed and tested for high-power and hard use including off-roading, pulling, and drag racing, this tubular steel support links the Allison rear housing to the transfer case to spread load and reduce driveline flex. Reinforcing the tail housing helps guard against cracks, leaks, and costly repairs often triggered by vibration from a failing U-joint or driveshaft. Finished in Fine Texture Black single-stage powder coat. Installs with basic hand tools using existing OEM fasteners; no removal of the transmission or transfer case is required.
