Product Description
Upgrade your 68RFE with the TRANSGO RFE-ACMPST-KIT Billet Accumulator Piston Kit, a smart transmission reliability upgrade for 2007.5-2018 Dodge Ram trucks equipped with the 68RFE behind the 6.7L Cummins. This kit replaces failure-prone OE-style accumulator pistons with billet aluminum pistons designed to resist cracking, improve piston stability, and deliver stronger sealing inside the valve body. With five billet accumulator pistons and 15 scarf-cut PTFE rings, this kit is built to help correct wear issues caused by side-loading and improve long-term hydraulic control. It is a drop-in style upgrade with no special tooling required, making it an excellent choice for rebuilding, preventative maintenance, towing applications, and transmission durability upgrades.
