Zipper’s Gen 2 Stage 3 Muscle Kit for 2024 and later Gen 2 Milwaukee-Eight® Helix Models

FOR 2024-Up 2nd GENERATION HELIX M8

The Stage 3 Muscle Kit is Zipper’s most popular performance kit for Milwaukee-Eight® engines! Make over 150 Ft-lbs and 165 HP that’s reliable and streetable!

Developed for the experienced rider that wants Performance, Reliability and the widest power curve in its class! The Stage 3 Muscle kit matches our Stage III M8 headwork blueprinting with our Red Shift 552 camshaft and 4.25” cylinder kit that results in big power across the entire RPM range. HUGE torque as soon as you open the throttle, and carries it across the RPM range to provide instant acceleration from any RPM. Compression is set to a relatively modest 11:1. It has an amazing sound at idle and under load!

The key to this great power is the carefully engineered combination of airflow, camshaft timing, compression, displacement and Zipper’s legendary commitment to testing and machining detail. All of these components are produced in-house at Zipper’s so you can be assured of the highest quality and reliable results! Tire life not guaranteed!
