Allison 4X4 Transfer Case Brace 2001-2007 LB7/LLY/LBZ Duramax, powder coated in Cat Yellow. 2001-2007 LB7/LLY/LBZ Duramax Allison Transfer Case Braces have been developed and tested for use on high horsepower Duramax applications, adding significant strength and reducing driveline flex common to extreme use such as off-roading, pulling, and drag racing. Helps eliminate the possibility of a cracked transmission tail housing on your Allison transmission from driveline vibrations due to things like a damaged u-joint or driveshaft by spreading the transfer case load across the transmission center section.

Key Features

  • Installs easily with basic hand tools. No removal of transmission or transfer case required.
  • Fabricated tubular steel support connects rear housing of Allison transmission to transfer case reinforcing the weaker tail housing section to eliminate flex caused by driveline vibrations which can result in a cracked housing, fluid leaks, and expensive transmission and transfer case damage.
  • Uses existing OEM Fasteners
  • Custom Single Stage Powder Coating

Fitment

  • 2001-2007 Chevrolet / GMC 2500 / 3500 HD 6.6L Duramax
