S&S SuperstockT 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; like more than a few of us found out the hard way. These S&S SuperstockT cases can be used for both stock replacement and racing applications. Important to the engine builder are the substantial savings in labor when using S&S cases. These cases come ''set up'' with sprocket shaft Timken main bearing races and cam needle bearings installed and 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 and a special S&S design alternator stator plug clamp screw. 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"; no additional clearancing for strokers will be necessary. S&S cases come complete with assembly instructions. Note: For 84-E85 Evo Big Twin models you must use a L85-91 style cylinder head bolt kit. These can be ordered separately as MCS 505266 (Gardner-Westcott) or 989599 (Colony) in standard lengths only.

Used with engines that have standard 5.550" length cylinders. Pushrods are non-adjustable and can be used with hydraulic operated tappets only. Pushrod sets are manufactured of 7/16" O.D. chromoly steel tubing with pressed-in and heat treated steel ends. This combination provides maximum strength and durability; regardless of performance application. Note: Stock cylinders are 5.550" with cylinder height specifications based on crankcases with stock Evo B.T. deck height. Note: Some large bore S&S engines have crankcases with a higher deck height and therefore shorter cylinders but stil may require the same length pushrods.
