Engine Case - 4.125" Bore w/Stock Stud Pattern - 88A Engine Type - Wrinkle Black - Twin Cam

The S&S CYCLE Twin Cam 88A engine case with a 4.125-inch bore is designed specifically for stock Harley-Davidson chassis, accommodating both carbureted and EFI systems. Crafted for durability and strength, this replacement twin cam "A" engine case offers greater overall robustness compared to stock crankcases, ensuring long-lasting performance under demanding conditions. The case features high-quality Timken®-style sprocket shaft bearings, providing reliable support for the engine's moving parts and reducing wear over time. All passages between the crankcase cam support plate are sealed with O-rings, preventing leaks and maintaining internal pressure integrity. This design ensures the engine operates smoothly and efficiently, minimizing oil carry-over and scavenging issues thanks to the integrated S&S crankcase breather reed valve. The case's compatibility with most stock components simplifies installation, while the rear motor mount bolts directly to the stock transmission, maintaining full compatibility with the primary drive system and charging components. Made in the USA, this engine case is a dependable choice for custom builds and rebuilds alike. Please note that installation requires a skilled technician, who must verify all clearances and assembly specifications to ensure proper fit and function. Whether upgrading an existing engine or building a new one, the S&S CYCLE Twin Cam 88A engine case delivers quality, strength, and compatibility for Harley enthusiasts seeking reliable performance.
