Power Pack - 4.375" Stroke - Oil Cooled - Black w/Highlights - M8

The S&S CYCLE Power Pack (Part Number: 310-1056C) is a high-performance bolt-on upgrade designed for M8 engines, offering significant power and reliability enhancements. Featuring a 4.375-inch stroke, this kit is engineered with precision and durability in mind, making it ideal for serious enthusiasts seeking to maximize their engine's potential. The kit includes forged pistons, a comprehensive oil pump and cam plate assembly, pushrods, tappets, and tappet cuffs, all crafted to exacting standards in the USA.
Constructed from billet aluminum, the oil pump and cam plate incorporate removable passage plugs for easy servicing and feature independent scavenge sections for the flywheel cavity and camchest. Debris screens in both scavenge pickups and a magnet in the camchest help prevent debris from entering the oil pump, safeguarding your engine. The design achieves a 44% increase in supply side flow and a 58% increase on the scavenge side, promoting superior oil circulation and cooling. An adjustable pressure relief valve allows fine-tuning of oil pressure with the unit installed in the engine, ensuring optimal performance.
The quickee pushrods are designed for quick installation and durability, enhancing valve train efficiency. Tappets are hand-assembled with tight tolerances to ensure low leak-down rates, reducing valve train noise from startup to shutdown. Tappet cuffs feature a hard anodized black coating and billet aluminum construction, providing stability at high lifts and RPMs. This comprehensive power pack delivers the performance, reliability, and ease of maintenance that serious riders demand, making it an excellent choice for upgrading M8 engines for street or strip applications.
