MUGEN MRX-5 7075-T6 Flywheel by Arrowmax AM-MRX5-H0778  [AM-MRX5-H0778]

Flywheel for MRX-5

This Arrowmax AM-MRX5-H0778 flywheel is an RC-scale replacement component machined from 7075-T6 aluminum, intended for use with Mugen MRX-5 chassis layouts. The part focuses on consistent rotational behaviour rather than adding speculative performance claims, serving as a drop-in option where the stock flywheel limits tuning resolution.

Fitment and role: designed to fit the MRX-5 driveline area and to work with standard clutch and engine assemblies used on that chassis, the flywheel affects spin inertia and throttle response; installers will remove the original unit and refit this part in the same location, verifying alignment and secure fastening before running the car.

Use this flywheel when you need a durable aluminum replacement that maintains consistent rotational characteristics for chassis setup and fine-tuning; check fitting and balance during installation and re-test throttle mapping after fitment.
