About this product
Upgrade your Harley-Davidson engine with the S&S Cycle Super Stock® Alternator Style Engine Case. This high-performance engine case is designed for durability and optimized oil scavenging, ensuring your engine runs smoothly and efficiently. Proudly made in the USA, this case provides a solid foundation for your high-performance build.
Description
The S&S Cycle Super Stock® engine case is machined to accept an oil filter assembly that mounts on the front, similar to stock motor cases. All races are line-honed, and the breather cavity is precision-machined to optimize breather timing for maximum oil scavenging. Designed for a 3.5" stock bore cylinder, this case accommodates strokes up to 5" and most stock length connecting rods. It's also machined for EFI fitment, making it compatible with modern fuel injection systems.
