The S&S CYCLE 124" Power Package with gear drive, part number 310-1058A, is a high-performance upgrade designed for serious motorcycle enthusiasts. This kit features a precision-engineered 107-inch to 124-inch big bore kit that bolt-on directly to your engine, eliminating the need for case matching. Crafted with forged pistons and an 11:1 compression ratio, it delivers increased power and efficiency. The kit includes an oil pump and cam plate, both precision machined from billet aluminum with a striking blue anodized finish, ensuring durability and a professional appearance. Passage plugs are removable for easy servicing, and independent scavenge sections for the flywheel cavity and cam chest enhance oil flow and reliability. Debris screens in both scavenge pickups and a magnet in the cam chest help prevent contaminants from entering the oil pump, extending the lifespan of your engine components. With increased flow capacity on both feed and scavenge sides, this kit optimizes oil circulation for high-performance applications. Adjustable pressure relief valves allow fine-tuning of oil pressure once installed in the engine. The package also includes high-quality pushrods—Quikee pushrods and S&S precision tappets—mounted with hard anodized black coating tappet cuffs for added strength and wear resistance. Constructed from stronger billet aluminum material, this setup reduces distortion under high stress, ensuring longevity and consistent performance. The kit's highlighted fin design and black pushrod tubes add a sleek, aggressive look to your engine, making it not only a performance upgrade but also a visual enhancement. Designed and made in the USA, this power package is ideal for riders seeking maximum horsepower and durability from their motorcycle engine.
