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

Precision flywheel for MRX-5 tuning

This Arrowmax AM-MRX5-H0778 flywheel is an RC replacement component machined from 7075-T6 aluminum and intended for use with Mugen MRX-5 chassis layouts. The unit emphasises consistent rotational behavior and predictable inertia rather than speculative power gains, making it a practical drop-in where the stock flywheel limits tuning resolution.

Fitment and role: made to sit in the MRX-5 driveline area and to interface with the standard clutch and engine assemblies used on that chassis, the flywheel modifies spin inertia and throttle feel; installers remove the original flywheel and refit this part in the same location, checking alignment and fastener security before the first run.

Choose this flywheel when you want a durable aluminum replacement that preserves steady rotational characteristics for chassis setup and fine-tuning; verify fit and balance during installation and adjust throttle mapping after fitting.
