Engineered 24T Pulley Tailored to Mugen MRX5

This Arrowmax AM-MRX5-H0251K pulley is designed for the Mugen MRX5 to deliver a neat balance of stiffness and weight reduction. Built from 7075 T6 aluminium, it supports consistent drivetrain behaviour during competitive running.

Precision Finish and Dirt Management

The pulley is CNC-machined to tight tolerances for dependable alignment and minimal wobble. A hard coat finish increases resistance to wear, while the perforated layout helps eject muck and prevents sticky operation on dusty circuits.

Suitable for Tuning and Replacement

As a direct-fit option for the MRX5, this lightweight pulley is well suited to anyone replacing a worn component or tuning for quicker response from the drivetrain. Installation is straightforward for experienced hobbyists.

Will this pulley fit other Mugen models?

This part is made specifically with the Mugen MRX5 geometry in mind. Other models may differ in shaft size or spacing so compatibility is not guaranteed without checks.

How does the hard coat help performance?

The hard coat shields the aluminium from scuffs and abrasion, keeping the pulley rounder for longer and reducing the chance of belt slip or uneven wear.

Any tips for balancing after installation?

After fitting, spin the drivetrain by hand to check for play. If vibration is noticed, inspect set screws and shaft seating; small shims or a careful re-torque can correct minor balance issues.
