About This Product

The S&S Super Stock engine case is a heavy-duty replacement for 1992 to 1999 style V-twin engines. Finished in a durable black coating, this case features a 3-1/2 inch bore and is designed to provide a much stronger foundation than factory castings. S&S utilizes high-strength aluminum and reinforced stress points to handle the increased torque of performance builds. The case comes with pre-installed studs and is machined to exacting tolerances to ensure proper alignment of the crankshaft and internal components. This is an essential component for riders building a ground-up custom engine or replacing a damaged factory crankcase. This product is sold individually.

Manufacturer part number: 31-0055.
