The S&S CYCLE Twin Cam 88A engine case is designed for use with stock Harley-Davidson chassis equipped with carbureted or EFI systems. Crafted for durability, this replacement twin cam "A" engine case offers greater overall strength than standard factory crankcases, providing enhanced reliability and performance. The cast aluminum construction is finished in a durable wrinkle black coating, giving your engine a sleek, professional appearance. This engine case is compatible with most stock components, simplifying installation and maintenance. It includes a specially designed S&S crankcase breather reed valve that effectively eliminates oil carry-over and scavenging issues, helping to keep your engine cleaner and running smoothly. The case features strong Timken®-style sprocket shaft bearings and all passages between the crankcase cam support plate are precisely O-ring sealed, ensuring robust sealing and oil retention. The rear motor mount bolts directly to the stock transmission, maintaining full compatibility with the stock primary drive, charging system, and other OEM parts. Made in the USA, this engine case requires a skilled technician for proper installation. The assembler must verify all clearances and assembly specifications to ensure optimal performance and longevity of the engine. Whether you're building a custom Harley or replacing worn components, this engine case provides a reliable foundation for your high-performance build.
