About This Product
This S&S forged stroker piston kit is engineered for 1941 to 1984 Big Twin engines, including Knucklehead, Panhead, and Shovelhead models equipped with stroker flywheels. These .020 inch oversize pistons are designed for 3-7/16 inch or 3-1/2 inch cylinders and provide varying compression ratios based on your stroke: approximately 8.4:1 for a 4-1/2 inch stroke, 9.4:1 for 4-5/8 inch, and 10.8:1 for 4-3/4 inch. The forged alloy construction and specialized skirt profiles ensure a quiet, long-lasting engine. Sold as a set, the kit includes wrist pins, clips, and rings. Professional installation is highly recommended to ensure all components are properly matched and cleared for your specific stroker build.
Manufacturer part number: 106-5529.

41-84 Big Twin with 84" (4-1/2" stroke); 86" (4-5/8" stroke) & 88" (4-3/4" stroke) engines
