2001-2007 Duramax Allison 4X4 Transfer Case Brace, Gloss Black (WCF100130-GB)

A tubular steel brace that ties the tail housing of the Allison transmission to the transfer case on 2001-2007 LB7, LLY and LBZ Duramax 4x4 trucks. High-horsepower trucks that tow, pull or drag race put a lot of driveline load through that tail housing, and this spreads it across the transmission center section instead of letting the housing flex and crack.

Installs with basic hand tools using the existing factory fasteners. Nothing has to come out of the truck. Powder coated in your choice of Wehrli colours.
