MUGEN MTX 20T 7075 Hard Pulley Upgrade - AM-MTX-T2202I by Arrowmax  [AM-MTX-T2202I]

MUGEN MTX Series Replacement Pulley

The Arrowmax AM-MTX-T2202I is a 20-tooth pulley machined from 7075 aluminium as a direct replacement or performance upgrade for compatible MUGEN MTX drivetrain assemblies. Its hardened aluminium construction is aimed at improving wear resistance and keeping tooth geometry stable across regular club and track use.

Fitting is straightforward for experienced hobby technicians: remove the stock pulley, inspect the shaft keyway and mating faces, slide the Arrowmax pulley into position and secure with the original hardware. After installation, confirm spur gear alignment, check adjacent bearings and verify pinion engagement, adding shims where necessary to prevent binding.

For tuners, this pulley provides consistent tooth engagement and dimensional stability during repeated runs. Treat it as an aftermarket accessory and include it in routine maintenance inspections, especially when you change motor or spur gear ratios.
