Super Stock Engine Cases / '92-'99 Evo Big Twin

Heat treated aluminum Super Stock engine cases from S&S for '92-'99 Evo Big Twin rebuilds.

Rebuilds and big bore builds both start with cases you can trust. S&S casts the Super Stock from A356 T-6 heat treated aluminum alloy, line hones all the races, and precision machines the breather cavity to optimize breather timing for maximum oil scavenging. The cases are machined to accept a front mount oil filter assembly and machined for EFI fitment, and they come with a deep parts list: crankcase bolts, cylinder studs, Timken sprocket shaft bearing assembly, pinion race, cam needle bearing assembly, fittings, plugs, and instructions. Choose standard bore or 3.625" big bore.
