GMC Sierra Transfer Case Brace - Wehrli - Gun Metal - 11-19. Heavy-duty support that ties the Allison transmission to the transfer case to control driveline flex under hard use.

Developed for high-horsepower Duramax applications, this brace strengthens the vulnerable tail-housing area by spreading transfer-case load into the transmission center section. It helps guard against cracks from vibration caused by damaged U-joints or driveshafts and reduces flex that can lead to leaks and costly repairs. Fabricated tubular steel construction uses OEM fasteners and installs with basic hand tools.
