About S&S Cycle
S&S Cycle has built American V-twin performance parts in Viola, Wisconsin since 1958 — flywheels, carburetors, cams, cylinder heads and complete crate engines. When a Harley owner talks about a 124, a 128 or a 131 build, they are usually talking about S&S. Few names carry more weight with engine builders in this space.
Keep your Milwaukee-Eight running strong with a fresh S&S Cycle throttle body gasket. This precision-engineered replacement seal prevents vacuum leaks at the critical throttle body-to-manifold interface, ensuring consistent engine performance. It's a small part that plays a big role in your M8's efficiency.

Common questions
Will this fit my Twin Cam Harley?
No, this S&S Cycle gasket is specifically designed for Milwaukee-Eight (M8) engines. Twin Cam models require a different part number.
Is this the same quality as an OEM Harley gasket?
S&S Cycle manufactures this gasket to OEM specifications, making it a direct replacement for the factory throttle body gasket on your Milwaukee-Eight.
Why would I need to replace this gasket?
Throttle body gaskets can degrade over time due to heat and engine vibration, leading to vacuum leaks that affect performance and fuel economy. Replacing it ensures a proper seal.

Perfect fit for a bike with small bars. I’m running Z Bars on a 77 big twin. Just the right length. Perfect thread engagement and nipple length for Super E.
