A1-TCB-08 Transfer Case Brace for your 2007.5-2010 GM 6.6L Duramax helps
provide support to your transmission. Due to the cantilever effect of
the rear trans mount, the transmission rear adapter housing is prone to
cracking. The slightest amount of rear drive shaft vibration can result
in a very expensive transmission repair. Help your transmission with
this easily installed brace. Installs in less than 30 minutes with no
special modifications or tools required.
