GMC Sierra Transfer Case Brace - Wehrli - Brizzle Blue - 07-10. Purpose-built for 2007.5-2010 Duramax LMM trucks with the Allison transmission, this brace adds targeted support where the drivetrain needs it most.

Developed and tested for high-power use, this fabricated tubular steel brace ties the rear Allison transmission housing to the transfer case, helping spread load through the transmission center section. By curbing driveline flex and vibration from issues like damaged U-joints or driveshaft imbalance, it helps prevent cracked tail housings, fluid leaks, and costly repairs. Finished in durable Brizzle Blue single-stage powder coat. Installs with basic hand tools, requires no removal of the transmission or transfer case, and reuses existing OEM fasteners.
