124" Power Package - Chain Drive - Highlighted Fins - Chrome Pushrod Tubes - 107" M8

Upgrade your Harley-Davidson M8 engine with the S&S Cycle 124-inch big bore power package, designed for maximum performance and durability. Crafted in the USA, this bolt-on kit increases engine displacement from 107 to 124 inches, delivering enhanced power and torque without requiring case matching. The kit features forged pistons with an 11:1 compression ratio, providing increased combustion efficiency and improved engine responsiveness.
Constructed from precision-machined billet aluminum, the components are finished with a durable blue anodized coating that resists corrosion and enhances visual appeal. The high-flow oil pump and cam plate ensure optimal lubrication and oil flow, while removable passage plugs facilitate easy servicing. Independent scavenge sections for the flywheel cavity and cam chest, along with debris screens and a magnet in the cam chest, help prevent debris from entering the oil pump, extending engine life.
This package also includes high-quality pushrods, Quikee pushrods, and S&S precision tappets with hard anodized black coatings, ensuring reliable valve operation under demanding conditions. The adjustable pressure relief valve allows for precise tuning while installed in the engine, optimizing performance and safety. The kit's billet aluminum construction offers superior strength compared to stock parts, eliminating distortion and providing long-lasting reliability. With highlighted fins and chrome pushrod tubes, this power package not only boosts performance but also enhances the aesthetic appeal of your motorcycle.
