Engineered For Precision Fitment And Extreme Durability

The PPE 128045800 Transfer Case Gasket is a critical sealing component designed for the connection between the Allison 1000 or 2000 Series transmission and the transfer case in 2001-2010 GM Silverado and Sierra HD models equipped with the Duramax 6.6L. It is precision cut for exact fitment, ensuring the proper alignment and sealing surface needed to eliminate leaks under high-stress operating conditions. The gasket is made from MP-15, an advanced material known for its ability to resist heat, pressure, and deformation even after prolonged exposure. This makes it ideal for diesel-powered trucks that see heavy towing, off-road use, or higher horsepower applications. The design not only prevents fluid loss but also contributes to long-term drivetrain reliability. Unlike low-grade gaskets that can fail over time, this one is engineered to match the durability of your Allison transmission. It installs easily and delivers dependable performance from the first mile.
