MUGEN MRX5 48T Hard-Coated Pulley for Belt Drive - Arrowmax AM-MRX5-H2202  [AM-MRX5-H2202]

Arrowmax AM-MRX5-H2202 pulley summary

The Arrowmax AM-MRX5-H2202 is a precision CNC pulley made as an aftermarket option for the MUGEN MRX5 belt-drive layout. Machined from 7075 T6 aluminium and finished with a wear-resistant hard coat, it reduces unsprung rotating weight while protecting the contact surfaces from abrasion. The side perforations help clear grit that can build up near the belt path.

As a direct-fit replacement for the stock MRX5 pulley, this unit aims to maintain consistent belt engagement and stable rotational inertia. The combination of lower mass and durable finish supports crisper throttle and braking transitions on on-road RC cars when properly aligned and torqued.

Fit this pulley when refreshing worn MRX5 drivetrain parts or when experimenting with lighter rotating components; always check belt tracking and re-torque fasteners after the first run.
