Forged 3-7/8in. big bore pistons are compatible with stock or S&S Super Stock cylinder heads in Harley-Davidson Twin Cam 88 and Twin Cam 88B engines.
These pistons are designed to increase displacement of stock Twin Cam 88 engines to 95in. and have a 5. 3cc pop up dome for a slight compression increase.
Piston weight is virtually identical to that of stock pistons in 88in. motors, so rebalancing the stock flywheels is not necessary when installing S&S 92-1200 pistons.
