S&S® Twin Cam® ‘A’ style (non-counterbalanced) engine cases are available for the builder who wants to replace a worn out set or use as a rock-solid foundation for a large displacement engine. Made from high strength heat-treated aluminum castings, these cases incorporate additional clearance for longer stroke crankshafts and high lift cams. Additional support has been added around the engine mounts and Timken® output bearings for greater overall strength than stock cases in a high performance application. Includes cylinder studs, Torrington cam bearings, Timken® sprocket shaft bearing and assembly hardware. Compatible with stock components in Twin Cam® applications but requires year-specific oil line/installation kit. 2007-up cases require a simple transmission case modification; drilling fixture jig available, recommended for easy installation. A special version of these cases includes an Evolution®-style rear mount that allows mounting in any EV-style chassis, and accepts 1999-2005 Twin Cam® engine components for those that want to update their EV-based bike to a Twin Cam® style engine.
