S&S CYCLE 132" Power Package Engine Performance Kit - Gear Drive - Oil Cooled - Non-Highlighted Fins - M8 310-1234

If you're running a 114" or 117" M8 and want serious power without a complete engine rebuild, the S&S Cycle 132" Power Package delivers displacement and performance in one bolt-together solution. This kit transforms your existing engine while preserving the original serial number and stock crankcase—critical for documentation and resale value. You get a professionally engineered, dyno-matched package that retains factory engine height, making it ideal for bikes where hood clearance or frame fitment is a concern.

The engineering here is substantial. S&S matched the big-bore cylinders with a performance 550 cam and dedicated oil pump, then added independent scavenge sections for the flywheel cavity and cam chest to ensure proper oil management under high-output conditions. The adjustable pressure relief valve can be tuned without engine removal, and magnetic debris traps in the cam chest protect internal components. This is a kit built by people who understand forced induction and high-RPM reliability.
