Billet Reverse Servo Piston Kit for 5.9L Cummins

If you're putting power through a 47RE or 48RE transmission, upgrading the reverse servo piston isn’t just a good idea—it’s a must. The ATS Billet Reverse Servo Piston Kit is built to replace one of the more failure-prone components in these transmissions with something far more durable and reliable. It’s a simple upgrade that can make a big difference in how your Ram performs under pressure. This kit is designed for 1996–2007 Dodge Ram 2500 and 3500 trucks equipped with the 5.9L Cummins. Also known as the low/reverse accumulator piston, the factory version is known to crack or wear out over time—especially in trucks that tow heavy or have been tuned for more power. ATS solves that issue by machining this piston from high-quality billet aluminum, giving it the strength needed to handle high-load situations without flinching.

Fits: 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007 Ram 5.9L Cummins
