About This Product
This S&S big bore piston kit is the plus ten thousandths oversize version for Milwaukee-Eight engines being bumped from 107 to 124 inches. Featuring an 11.1:1 compression ratio, these forged pistons are built for serious performance and durability. The kit comes complete with pistons, rings, wristpins, and clips. It is designed for use with 4.250-inch big bore cylinders and is compatible with the stock 4.375-inch stroke found in 2018 to 2024 Softail and 2017 to 2024 Touring 107-inch models. As with any high-performance build, we suggest using S&S 550 series cams and ensuring all gaskets, like the 591056 kit, are sourced separately for a proper seal.
Manufacturer part number: 920-0141.
