MRX-5 Aftermarket Pulley Kit 7075 Hard Aluminum - MUGEN AM-MRX5-H2201  [AM-MRX5-H2201]

MRX-5 pulley replacement

The Arrowmax pulley set is produced as a direct-fit aftermarket replacement for the MUGEN MRX-5 chassis. Machined from 7075 hard aluminum, the components are aimed at dimensional stability and wear resistance so drivetrain behaviour stays repeatable during setup and track use.

Installation is straightforward for those used to MRX-5 maintenance: confirm pulley seating on the spur and pinion, check bearing fit, and rotate the assembly by hand to ensure smooth operation before final assembly. The set is intended to make gearbox diagnosis and fine tuning easier by offering a reliable interface in the transmission area.
