Star M8 Billet Compensator Ramp
Engineered to protect your entire driveline investment, this precision billet compensator is one of the most critical upgrades you can make to your Milwaukee-Eight engine.
 
Part Description
The compensator is one of the most overlooked — and most consequential — components on your Milwaukee Eight. The factory compensator serves as the primary shock absorber between your crankshaft and drivetrain — shielding your flywheel assembly, primary chain, chain adjuster, clutch basket, and transmission from the constant torsional stress generated at low speeds, idle, and part-throttle operation.
 
Stock M8 compensators are notoriously brittle and fail unexpectedly without signs or warnings. When that happens, it is like tossing a grenade under your bike - destruction everywhere and you are left stranded and stuck with a $2k - $4k repair build.
 
Our Star M8 billet compensator replacement is built to tighter tolerances with superior materials, delivering smoother engagement, reduced drivetrain noise, and long-term protection for the components behind it — saving you from far more costly repairs down the road. We guarantee our compensator will not break! 
 
This compensator upgrade is the perfect match to any cam purchase. With increased torque, you really should have this part to finish the build.
