Upgrade your Harley-Davidson M8 engine with the S&S Cycle 132" Power Package Performance Kit, part number 310-1234. Designed for precision and durability, this kit transforms the stock 114" or 117" oil-cooled M8 into a robust 132" engine, enhancing power and performance. The kit features a gear drive timing system that ensures reliable timing accuracy while operating smoothly under demanding conditions. Its oil-cooled design maintains optimal operating temperatures, providing consistent performance during extended rides. The kit is compatible with stock crankcases and retains the original engine height, making installation straightforward without the need for significant modifications.
The high-performance conical single-wire S&S valve springs optimize valve control at high RPMs, contributing to overall engine stability. The big bore cylinders are matched with a performance cam and cam plate, along with an oil pump, to maximize airflow and power output. An integrated magnet in the cam chest helps prevent debris from entering the oil pump, promoting engine longevity. Independent scavenge sections for the flywheel cavity and cam chest facilitate maintenance and improve oil flow. The inclusion of MLS (multi-layered steel) head gaskets ensures a reliable seal under high-pressure conditions.
Additional features include removable passage plugs for ease of servicing, debris screens in both scavenge pickups to trap contaminants, and a performance-matched 550 camshaft for improved throttle response. The kit preserves the stock engine serial number, maintaining compliance with regulations. A decorative cam cover badge enhances the engine's aesthetic appeal. Made in the USA, this performance kit is designed for serious riders seeking increased horsepower, torque, and engine durability without sacrificing originality or reliability.
