Overview of the Arrowmax AM-MRX5-H2202 pulley

The Arrowmax AM-MRX5-H2202 is an aftermarket pulley crafted for the MUGEN MRX5 belt-driven on-road models. Constructed from 7075 T6 aluminium with a hard coating, it balances a lighter profile with stronger surface resistance to wear. The perforated sides help eject particles that otherwise collect near the belt contact area.

Engineered as a direct replacement, the pulley keeps belt engagement predictable and lowers rotating inertia, which can sharpen the car's response under acceleration and during braking. Proper alignment and secure mounting are essential to take full advantage of the component.

Specifications

  • Item: Pulley 48T 7075 Hard
  • Material: 7075 T6 aluminium, hard-coated
  • Model Number: AM-MRX5-H2202
  • Compatibility: MUGEN MRX5

Choose this pulley when replacing an aged MRX5 unit or when testing lighter rotating parts to refine drivetrain feel; always verify clearance and torque settings on installation.

Does this fit MRX5 gearboxes directly

The part is designed for MRX5 belt systems and normally fits without modification, but double-check bore and key alignment before final fitment.

What cleaning is recommended after running

Clean out the side holes and the belt seating surface with a soft brush and inspect for scoring; avoid harsh abrasives that could damage the hard coat.

Will aluminium reduce performance compared to steel

7075 T6 aluminium lowers rotational weight compared with steel, often improving transient response while maintaining adequate strength when properly coated.
