S&S press in pinion shaft assembly for S&S SF flywheels for 1999 - up Harley-Davidson® Twin Cam 88® and Twin Cam 96™ Engines. Comes complete with matching nuts and keys. These are intended as replacement parts when rebuilding S&S flywheel assemblies. Many shops may not have the equipment needed to repair this style of flywheel. We suggest that these flywheels be sent back to S&S for rebuilding.
