Star M28 Milwaukee-8 Camshaft - .540 Lift
$369.95
Star M28 Milwaukee-Eight Camshaft — .540 Lift
A dual-profile, high-lift cam engineered for riders who want more — more torque, more top end, and more of that aggressive chop that turns heads at every stoplight. This cam is the biggest bolt-on camshaft compatible with a stock M8 Gen II (2024-2026 models).
Part Description
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 that leaves no doubt about what's under the covers.
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.

Exhaust pairing matters: Star Cams will perform with all pipe configurations, but exhaust selection has a meaningful impact on results. Short exhaust systems create sound wave differentials that negatively affect low-RPM tune quality — a condition that cannot be fully corrected through tuning alone. For the smoothest low-end torque curve, a long 2-into-1 exhaust is strongly recommended. Trusted options include D&D, Fuel Moto, Bassani, ThunderHeader, and Krome Werks.
Professional tuning recommended for best results.
