GMC Duramax L5P Transfer Case Brace - Wehrli - Candy Red - 11-19. A purpose-built support for 2011–2019 LML/L5P trucks with the Allison, engineered to add strength and curb driveline flex under hard use.
Developed and tested on high-horsepower Duramax applications, this fabricated tubular steel brace ties the rear housing of the Allison transmission to the transfer case. By distributing load into the transmission center section, it helps reduce the chance of cracked tail housings and fluid leaks caused by vibrations from issues like damaged u-joints or driveshafts. The Candy Red single-stage powder coated finish stands out, and installation is straightforward with basic hand tools—no transmission or transfer case removal required.
