MRX-5 Hard Pulley Set 7075 Aluminium - MUGEN AM-MRX5-H2201  [AM-MRX5-H2201]

Replacement pulleys for MRX-5

The Arrowmax pulley set is supplied as an aftermarket replacement for the MUGEN MRX-5 chassis. Crafted from 7075 hard aluminium, the parts emphasise dimensional accuracy and surface durability to help maintain predictable drivetrain behaviour while tuning or racing.

Fitment follows standard MRX-5 service routines: check pulley seating with the spur and pinion, confirm bearing location and fit, and manually rotate the assembly to ensure quiet, smooth motion before completing reassembly. These pulleys are intended to make diagnosing transmission play and mesh easier during setup.
