Description

Part #: 320-0361

S&S (R) 4-3/8" Stroke Flywheel Assembly W/O Sprocket Shaft Bearing Race For 1999-'06 Non-balanced HD (R) Big Twins (Except 2006 Dyna Models).

MIA's Description

Designed for 1999-2006 Twin Cam engines, this S&S CYCLE 320-0361 flywheel assembly is made from high-quality 4140 steel. It features a 3-piece design with an integral main shaft and a larger 1.671-inch crankpin for enhanced strength. It fits directly into stock crankcases without modifications. Made in the U.S.A., it comes without a sprocket bearing race, allowing compatibility with Timken bearing conversions (sold separately).
