Product Description
S&S Super Stock Alternator Style Crankcase for Harley Davidson
S&S Superstock crankcases, made from 356-T6 aluminum, are much stronger than the OEM case. OEM cases can / may break in high performance or even stock applications, as many of us have found out the hard way. These S&S Superstock cases can be used for both stock replacement and racing applications.
The S&S crankcases offer substantial time savings when building. These cases come set up with sprocket shaft Timken main bearing races and cam needle bearings installed as well as pinion shaft main bearing race pressed in and line-honed. Additional parts that are supplied include Timken sprocket shaft bearings, cylinder studs, nickel plated case bolts, crankcase fittings, oil pressure sensor, timing & magnetic crankcase drain plugs.
The flywheel scrapers are machined to match the original 8-1/2" diameter flywheels. S&S cases maximize crankcase oil scavenging efficiency by using a ported design breather passageway.
S&S cases are clearanced up to and including 5" stroke, no additional clearancing for strokers will be necessary.
Note: For 84-E85 Evolution Big Twin models you must use a L85-91 style cylinder head bolt kit. These can be ordered separately as A266-407671 (Gardner-Westcott) or A599-892004 (Colony) in standard lengths only.
