Overview

The S&S Cycle 920-0073 is a set of low compression stroker pistons with a 3-7/16" standard bore. These forged pistons are designed for 1936-'84 Harley-Davidson Big Twins and are intended for use with S&S stroker flywheels. Depending on the flywheel stroke used (4-1/2", 4-5/8", or 4-3/4"), they can achieve displacements of 84", 86", or 88" respectively, with corresponding compression ratios.

Constructed from modern alloys, these pistons feature advanced skirt profiles that allow for tighter fits, contributing to reduced engine noise and extended engine life. They are typically used in stock HD cylinders and may require purchasing pistons based on the necessary oversize.
