S&S Cycle Super Stock Generator-Style Crankcases

S&S Cycle Super Stock generator-style crankcases for Big Twin engines with stock bores are designed with a stock-like appearance and incorporate updated design features that improve overall engine strength and reliability. Select the crankcase to fit your engine.

Features and benefits:

* Pre-clearance for strokes up to and including 5 in.
* Motor mounts on crankcases for knucklehead engines are machined to fit stock 1936-47 frames. An adapter plate is included for 1948 and later-style frames
* All cases are designed for late style generator, two brush type with 5/16 in. mounting bolts to eliminate early generator cradle/mounting strap bosses for simplicity and economics
* Timken sprocket shaft main bearing, in all years, instead of stock-straight roller bearings; resulting in better flywheel assembly stability, placement and longer engine life
* Kits include crankcase assembly, all required hardware and bearings for installation

Note: All S&S crankcases use Timken style sprocket shaft bearings and 1958 and later pinion bearings. These cases will not accept stock 1957 and earlier flywheel assemblies.
