The Star M28 Milwaukee-8 Camshaft is a dual-profile performance camshaft purpose-built for the Milwaukee-Eight Gen II platform. With .540 lift and an intake closing point of 28° ABDC, the M28 delivers a broader, more aggressive power curve than the 30/30 — making it the ideal choice for riders looking to push their build further. The dual-lobe design puts low-RPM torque on the intake side and top-end power on the exhaust side, covering the full range of real-world riding demands. Expect an aggressive, unmistakable lope at idle.
High performance Lifter Guides are required. Star Gold Lifter Guides (M8726LG) recommended.
Designed specifically for H-D M8 2024-2026 models. However, this cam can be installed in all Gen I models (2017-2023) but requires high performance valve springs. Star M8 Valve Spring Kit (640SK-2) is recommended.
- .540 lift — higher lift profile for increased airflow and peak performance gains
- 2,000 to 5,500 RPM powerband — broad, usable range from low-speed cruising to highway pulls
- Dual-profile cam design — intake lobe optimized for low-RPM torque, exhaust lobe built for top-end power
- Aggressive idle lope — that classic, hard-hitting Harley sound (chop)
- Intentionally designed for 2024–2026 Gen 2 M8 engines but can run in Gen 1 engines with upgrades.
