S&S CYCLE Special Application Crankcase (Engine Case) for Evolution Big Twin Built for high-performance Twin Cam and Evolution Big Twin style builds, the S&S CYCLE Special Application Crankcase is engineered to support 4.000" bore cylinders with clearancing for stroker combinations up to 5.000" stroke . Key Features Special Application engine case designed for cylinder bores up to 4.000" Cam chest moved outward 0.250" to help the crankcase handle large bore sizes Clearanced for strokes up to 5.000" for stroker-ready performance Relocated cam chest oil pick-up boosts gear case scavenging and helps virtually eliminate oil carry-over at sustained high speeds Machined to accept the stock 1992–1999 Big Twin oil filter assembly Ported breather passageway with a machined breather window routes air/oil mist from the flywheel cavity to the cam chest with minimal restriction Flexible crankcase venting via two crankcase breathers , the cylinder heads, or both (S&S recommends using both crankcase breathers on engines larger than 95") Deck height: 5.875" Machined for a crank position sensor to enable EFI applications and simplify installation of S&S IST Ignition and VFI Fuel Injection (plug kit included for non-sensor applications) Made in the USA Specifications Brand: S&S CYCLE Product: Engine Case (Special Application) – Kit Riding Style: Street Color/Finish: Natural Weight: 34.2 lbs Dimensions: 17.81" x 14.44" x 12.06"
Designed for high performance engines with cylinder bores 4.000"
Cam chest is moved outward 0.250" to allow crankcases to handle large cylinder bore sizes
Clearanced for strokes as long as 5.000"
Relocated cam chest oil pick-up increases gear case scavenging and virtually eliminates oil carry-over at sustained high speeds
Machined to accept the stock oil filter assembly used on '92-'99 Big Twins
A ported breather passageway and a machined breather window allows the air/oil mist to flow from the flywheel cavity to the cam chest of the engine with the least possible restriction
Crankcase venting can be achieved via two crankcase breathers, the cylinder heads, or both; S&S recommends using both crankcase breathers in engines larger than 95"
Deck height is 5.875"
Made in the USA
Machined for installation of a crank position sensor which allows the cases to be used in EFI applications and also allows easy installation of S&S IST Ignition and VFI Fuel Injection; a plug kit is included for applications that do not use a crank position sensor.
All S&S crankcases manufactured after June 1, '08 do not have case interlock groove and ring and do not use case alignment studs. Case mating surface is flat, and cases are aligned with alignment dowels.
