GMC Sierra 2500HD Transfer Case Brace - Wehrli - Gloss Black - 2011-2019. Built for Duramax LML/L5P trucks with Allison transmissions, this brace adds critical support between the transmission and transfer case.

Developed and tested for high-power and hard-use conditions like off-roading, pulling, and track days, the welded tubular steel design reduces driveline flex and helps ward off costly tail-housing damage. By distributing transfer-case loads into the transmission center section, it helps minimize vibration-related issues such as cracks and fluid leaks. Finished in durable gloss black powder coat, it installs with basic hand tools, requires no removal of the transmission or transfer case, and reuses factory fasteners.
