Upgrade your Harley-Davidson M8 engine with the S&S Cycle 124" Big Bore Power Package Kit, part number 310-1054B. Designed and manufactured in the U.S.A., this bolt-on kit allows for a significant increase in engine displacement from 107 inches to 124 inches, delivering enhanced power and performance without the need for case machining. Crafted from precision-machined billet aluminum, the kit features a durable blue anodized finish that resists corrosion and provides a sleek look. The kit includes forged pistons with an 11.1:1 compression ratio, enabling higher airflow and combustion efficiency for more horsepower and torque. The oil pump and cam plate are integrated into the design, with removable passage plugs for easy servicing, ensuring long-term reliability. The inclusion of independent scavenge sections for the flywheel cavity and cam chest, along with debris screens in both pickups, helps maintain clean oil flow and reduces the risk of debris entering the oil pump. An integrated magnet in the cam chest further prevents debris from entering critical components, extending engine life. Both feed and scavenge passages are optimized for increased flow capacity, supporting higher engine demands. The adjustable pressure relief valve allows fine-tuning of oil pressure while the unit is installed in the engine, ensuring optimal lubrication. The kit also includes high-quality pushrods, Quickee-style pushrods, and precision T&S tappets with hard anodized black coating, providing durability and improved valve operation. The strong billet aluminum construction of the tappet cuffs eliminates distortions common in stock parts, maintaining proper valve timing and performance. Featuring highlighted fins and black pushrod tubes, this power package not only enhances engine performance but also adds a distinctive aesthetic touch to your motorcycle. Easy to install and designed for durability, the S&S Cycle 124" Power Package Kit is ideal for riders seeking increased horsepower, torque, and overall engine performance in a reliable, bolt-on package.
