These forged, 4" 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. The 92-1430 series is used in S&S 100" kits for Twin Cam 88 and Twin Cam 88B engines. Since the weight of the 92-1430 piston is virtually identical to the weight of the stock 88" piston, the stock 4" stroke flywheel assembly from 88" or 95" engines can be used without rebalancing when upgrading to a 100" engine with the S&S 4" bore top end. These are a flat top, oversized pistons made for high silicon forgings.
