PPE Transfer Case Brace (11-19 6.6L Duramax Sierra 3500 HD)Find parts that fit my vehicle

Description. 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 applications. Even a nominal 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.
