Mugen MRX5 Pulley 28T by Arrowmax AM-MRX5-H2201E  [AM-MRX5-H2201E]

28T 7075 Hard Pulley

The Arrowmax AM-MRX5-H2201E is a scale RC belt pulley made for the Mugen MRX5 chassis, machined from 7075 T6 aluminum and finished with a hard coating to improve wear resistance while keeping mass low. Its 28-tooth profile matches MRX5 belt drive layouts and the CNC machining ensures concentricity for smoother belt tracking during track use.

Side cutouts in the pulley body help shed debris produced by friction, reducing buildup that can disturb belt alignment. As a light alloy hop-up, this pulley focuses on repeatable belt engagement and longer service life compared with standard stamped parts.

Installation notes: confirm the pulley seats flush on the intended shaft and that the belt tension is set to the MRX5 manufacturer's recommendations to avoid premature wear. Regular inspection of the pulley bore and side holes for trapped grit will help maintain smooth operation.

Compatibility
