Chevrolet Silverado Transfer Case Brace - Wehrli - LB7/LLY/LBZ - Bronze Chrome - 01–07. Built for 2001–2007 Duramax/Allison trucks, this brace reinforces the vulnerable tail housing to help keep your driveline under control.

Developed and tested for high-horsepower Duramax applications, the Wehrli brace reduces driveline flex seen in hard use such as off-roading, pulling, and drag racing. The fabricated tubular steel support ties the rear housing of the Allison transmission to the transfer case, spreading load into the transmission center section to help prevent cracked housings, fluid leaks, and costly repairs. Installs with basic hand tools using existing OEM fasteners; no transmission or transfer case removal required. Finished in a durable Bronze Chrome single-stage powder coat.
