MUGEN MRX5 48T Hard-Coated 7075 Pulley Upgrade - Arrowmax AM-MRX5-H2202  [AM-MRX5-H2202]

Product outline for AM-MRX5-H2202 pulley

The Arrowmax AM-MRX5-H2202 is a CNC-made pulley intended for use with the MUGEN MRX5 belt-drive system. Built from 7075 T6 aluminium and treated with a hard coating, it provides a lighter profile with increased resistance to wear at the belt contact area. Perforated side panels assist in ejecting small debris and preventing buildup.

Designed as a direct replacement for the factory MRX5 pulley, this component targets stable belt engagement and reduced rotational inertia to help improve throttle response and braking feel on on-road RC cars. Accurate alignment and correct fastener torque are necessary for dependable performance.

Select this pulley when renewing MRX5 drivetrain parts or when testing lighter rotating components; always verify belt tracking and re-check torque settings after installation.
