S&S, flywheel assembly with 4-5/8" stroke crankshaft for M8

Without balancer gear. Connecting rods with full-width crankpin bosses for use with S&S pistons. Comes fully assembled with flywheels, connecting rods, rod bearings, pinion shaft and sprocket.
- Heat-treated 4140 material is harder and more than twice as strong as the original - The strongest assembly eliminates the need to weld the crank pin - S&S high-strength connecting rods are designed using Finite Element Analysis to eliminate weak points - Full-width connecting rods for the crank pin (requires S&S high-performance pistons) - Balanced for the weight of the S&S high-performance piston (1213g) - Perfect for gear-driven camshafts - Consistent balance and precision machining - Capable of higher RPMs for more available power
Note: Required for the installation of the big bore cylinder and piston kits 923194 / 923193 of 131" (4.250" bore) and S&&S 994438/994437 of 136" (4.320" bore).
Note: The sprocket gear is not included. See 923271 for the identical flywheel assembly with sprocket gear installed.
