S&S Super Stock Alternator Crankcase 3-1/2"

Perfect for stock replacement and high performance applications, these crankcases offer some unique features. Besides being machined for a crank position sensor, they are also compatible with stock flywheel assemblies, primary covers, gear covers and are clearance for 38 amp alternator stators.

Features and Benefits

• 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 1984-1991 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"
• Clearance for strokes as long as 5"
• Compatible with stock 1984-1999 flywheel assemblies, primary covers, gear covers, and clearance for 38 amp alternator stators, making them perfect for stock replacement or high performance applications
• Machined for installation of a crank position sensor. This allows the cases to be used in stock 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
• Made in the USA
