Chevrolet Silverado 3500 Transfer Case Brace - Wehrli - Brizzle Blue - 01-07. Built for 2001-2007 Duramax LB7/LLY/LBZ trucks with the Allison, this brace links the transmission to the transfer case to add support under hard use.

Developed and tested on high-power Duramax builds, it helps reduce driveline flex common in off-road, pulling, and drag racing. The tubular steel support ties the rear Allison housing to the transfer case, spreading load across the transmission center section to help avoid cracked tail housings, leaks, and costly repairs. Finished in Brizzle Blue single-stage powder coat, it installs with basic hand tools using existing OEM fasteners—no transmission or t-case removal.
