WHY HARLEY RIDERS CHOOSE THIS

S&S Cycle engineers these seals specifically for the higher combustion pressures and airflow demands of modern V‑twin configurations. The Black Viton formulation outlasts standard nitrile O‑rings by resisting fuel swelling and heat cycling, which keeps the intake tract leak‑free under hard acceleration. Riders trust this direct‑fit upgrade because it restores precise throttle response and stable idle without requiring machining or special tools. Its straightforward installation and proven material chemistry make it the go‑to replacement for anyone maintaining or rebuilding S&S cylinder assemblies.
