Description
- Cam chest is moved outward .250″ to allow crankcases to handle large cylinder bore sizes
- Relocated cam chest oil pick-up increases gear case scavenging and virtually eliminates oil carry-over at sustained high rpm
- 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″
- Clearanced for strokes as long as 5″
- 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

While the Special Application Crankcase was a bit pricey, this baby really improved performance for my Big Twin with thoughtful design features like the relocated oil pickup and machined breather passageway, though assembly instructions could’ve been clearer.
