Give Your 68RFE The Upgrade It Deserves

If your 68RFE is still running stock accumulator pistons and covers, you're leaving one of the transmission’s biggest weak points untouched. The ATS Accumulator Piston & Cover Kit is an easy, effective upgrade that gives your RAM 2500 or 3500 the durability it needs for real-world driving. Whether you’re towing a heavy load, running a tune, or just want your shifts to feel tighter and more controlled, this kit makes a noticeable difference. The factory parts are prone to blowouts under pressure, which can lead to soft shifts, clutch slip, or worse, outright failure. ATS solves this with a billet cover and precision-machined piston set built to handle serious line pressure without backing down. It's a no-brainer upgrade for any 2007.5–2018 Cummins owner looking to extend transmission life while improving drivability. If you're already in the valve body or planning a rebuild, this is the kind of part you don’t skip.

Built To Eliminate Flex And Restore Shift Control

The ATS 303-121-2326 Accumulator Piston & Cover Kit is engineered to replace the factory cast aluminum components found in the Dodge 68RFE’s accumulator circuit. Under normal use, the OEM parts can flex or even fail as line pressure increases, especially in trucks that tow frequently or run aftermarket tuning. This kit includes a billet aluminum accumulator cover and a high-quality piston set, both of which help maintain consistent hydraulic pressure during gear changes. By preventing blowout and improving fluid control, it supports cleaner, firmer shifts while reducing internal transmission stress. It is specifically designed for 2007.5–2018 RAM 2500 and 3500 models equipped with the 6.7L Cummins engine. This kit installs in the valve body area and is often upgraded during transmission service or performance builds. Manufactured by ATS in the USA, this component reflects the brand’s commitment to performance-driven reliability for hardworking diesel trucks.
