Allison Cracked transmission tail shaft housings (located between the transfer case and the transmission) are a common problem for GM Allison-equipped 4x4 pick-ups in off-road and drag racing situations. Even a normal amount of driveline vibration can cause the housing to fail, resulting in a transmission fluid leak or worse; internal transmission and transfer case damage. Once the housing cracks, repairing it requires removal of the transmission and transfer case.
PPE’s new Transmission Transfer Case Brace helps support the overhanging, heavy transfer case by spreading the load up and across the adaptor housing to the center section of the transmission.

PPE’s Transmission Transfer Case Brace utilizes two 304 stainless-steel 7/8 inch support tubes tied together with a thick 304 stainless-steel plate for increased strength and service life.

Mounting the brace is a quick and easy job that can be done without removal of the transmission or transfer case. No special tools required.

SunCoast Transfer Case Brace. 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.
