Description
Whether you’re building a high-output big-twin or refreshing a time-tested engine, the S&S Cycle 106-5520 piston kit delivers the strength and longevity you need for sustained performance. Forged construction resists detonation and wear far better than cast alternatives, while modern alloy chemistry and optimized skirt profiles minimize friction and keep combustion noise under control. This complete kit includes everything required for a proper rebuild—pistons, rings, wristpins, and clips—so you can focus on the machine work, not sourcing components.
