Description
This is a 4L80E dual seal accumulator piston SET for 4L80E series transmissions
- This set REQUIRES the later model 3/8″ (.375″) accumulator pin
- These 4L80E dual seal accumulator pistons have slightly higher spring preload than stock
- This set/kit includes two accumulator pistons, enough for one transmission
- Both accumulator pistons use two seals each to help eliminate pin wear, unlike the OE piston
- Our set solves the problem by providing two seals and the pin to stabilizes the piston in the bore
Upgrade your 4L80E series transmission with our 4L80E dual seal accumulator piston set – both pistons have two seals to eliminate pin wear.
