This is the Orange Frost version. Wehrli's transfer case brace for 2011-2019 LML and L5P Duramax trucks with the Allison transmission and 4x4 was developed on high-horsepower builds. It ties the Allison transmission's rear housing to the transfer case with a fabricated tubular steel support, spreading the transfer case load across the transmission so the weak tail housing is not carrying it alone. That reduces driveline flex and the vibration that cracks tail housings on trucks that are pulled, drag raced, off-roaded or simply making a lot of power.

Key Features
