Product Description
The ATS 303-021-2326 68RFE Accumulator Piston Kit is a critical upgrade for 2007.5+ 6.7L Cummins trucks equipped with the 68RFE transmission. Designed to replace the weak factory plastic pistons, this kit improves transmission durability, shift consistency, and long-term reliability.
The factory accumulator pistons are known failure points under increased power or heavy towing, often leading to slipping, inconsistent shifts, and premature transmission wear. ATS addresses this issue with precision-machined billet aluminum pistons that provide superior strength and resistance to heat and pressure.
This upgrade is ideal for stock, tuned, and high-performance Cummins applications looking to eliminate a common failure point while improving overall transmission performance.
FAQ
Q: What do accumulator pistons do in the 68RFE transmission?
A: Accumulator pistons help control hydraulic pressure during shifts, ensuring smooth and consistent gear changes.
Q: Why upgrade the factory pistons?
A: Factory pistons are prone to cracking or failure under stress. Upgrading to billet pistons increases durability and prevents transmission issues.
Q: Will this improve shifting performance?
A: Yes, it helps provide more consistent and controlled shifts, especially under load or increased power levels.
Q: Is this recommended for tuned trucks?
A: Absolutely. This is a highly recommended upgrade for tuned, towing, or performance applications using the 68RFE transmission.
