7075 T6 20T Pulley Optimised for MRX5

Refine your Mugen MRX5 drivetrain with the Arrowmax AM-MRX5-H0251B 20T pulley, precision machined from 7075 T6 aluminium for long life and reduced weight. The hard-coated surface adds wear resistance, while cutouts assist in ejecting dirt for smoother belt operation.

Fit and Function for Chassis Compatibility

Built to mate cleanly with the MRX5 chassis, this Arrowmax pulley maintains correct belt alignment and dependable engagement. The strong yet light alloy keeps rotational mass down without sacrificing durability under hard running.

Suited for Competitive Setups

As a 20T replacement pulley, it supports sharper throttle response and steadier acceleration, making it a sensible choice for racers tuning their setup for tighter lap times.

Can I run this with stock belts?

Yes, it works with standard belt types used on the MRX5, but check belt tension and alignment after fitting.

Does the finish resist scuffing?

The pulley features a hard coat that improves wear resistance compared with untreated aluminium surfaces.

Will changing to 20T alter the gearing?

The tooth count is fixed at 20T, so gearing effects depend on the rest of your drivetrain; confirm final ratios when swapping parts.
