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
- Stiffer springs are available
Upgrade your 4L80E series transmission with our 4L80E dual seal accumulator piston set – both pistons have two seals to eliminate pin wear.
