You are buying a dual seal accumulator piston SET for the 4L80E series of transmissions
- REQUIRES the later model 3/8" (.375") accumulator pin
- Accumulator pistons have slightly higher spring preload than stock, to help firm up shifs slightly
- This set includes two accumulator pistons - enough for one transmission
- Both accumulator pistons use two seals each, unlike the OE piston, to help eliminate pin wear
- This one solves the problem by providing two seals and uses the pin to stabilize the piston in the bore
- The seals are included, see our other auctions for more transmisson parts
