The PPE 129020710 Transfer Case Brace for your 2007.5-2010 GM 6.6L Duramax LMM is designed to help eliminate cracked transmission tail shaft housings (located between the transfer case and the transmission). This is a common problem for GM Allison-equipped 4x4 pick-ups in offroad 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.

PPEs new Transmission Transfer Case Brace helps support the overhanging, heavy transfer case by spreading the load up and across the adapter housing to the center section of the transmission. PPEs 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..

Most Popular Questions

I have a 2001 Suburban 2500 8.1L that I take to the dunes, and tow with. I have heard the weight of the transfercase can crack the 4L80E transmission tailshaft. I was looking at the PPE Allison trans brace, and would like something like that for my application. Is there anything available?

No. The PPE 129020710 Transfer Case Brace only works on 8.1L gas or 6.6L Diesel engines that are equipped with the Allison transmission.
