High Precision 24T Pulley for Mugen MRX5

Made for the Mugen MRX5, the Arrowmax AM-MRX5-H0251K pulley improves drivetrain efficiency without adding unnecessary mass. Machined from 7075 T6 aluminum, it balances strength and weight savings to suit competitive track use.

CNC Machining and Protective Coating

Manufactured with CNC accuracy, this 24T pulley delivers a tight fit and consistent performance. Its hard-coated surface increases wear resistance, while the drilled holes help shed grit and keep the pulley turning cleanly during fast runs.

Practical Upgrade for Club and Race Use

Whether you are refreshing worn parts or optimising your setup, this lightweight pulley integrates smoothly with the Mugen MRX5 chassis to provide dependable power transfer and minimal drivetrain loss.

How do I fit the Arrowmax AM-MRX5-H0251K to my MRX5?

Remove the stock pulley and check pinion alignment before fitting the Arrowmax unit. Ensure the set screw is tightened to the recommended torque and confirm belt or gear mesh is correct for smooth operation.

What routine care keeps the pulley running well?

Wipe the pulley free of loose debris after each session and inspect the hard coat for chips. Lightly clean the drilled holes with a brush to prevent buildup that can affect balance.

Can I use this pulley on rough or dirty tracks?

Yes, the hard-coated 7075 T6 construction is suited to demanding environments, though frequent cleaning is advisable to maintain peak performance on abrasive surfaces.
