MRX-5 pulley replacement part

This Arrowmax pulley set is offered as a replacement component for the MUGEN MRX-5 chassis. Turned from 7075 aluminium, the set aims to deliver consistent dimensions and improved surface robustness so drivetrain behaviour remains predictable when making setup changes.

Installation follows familiar MRX-5 procedures: verify correct pulley seating on the spur and pinion, inspect bearing fits, and hand-rotate the gearbox assembly to confirm smooth movement before finishing the rebuild. The pulleys help technicians and racers isolate slack and fine tune gear engagement.

Will this pulley set work with MRX-5 gear ratios?

The set is intended for MRX-5 transmissions; check the pulley offsets and bore size against your current gearing to ensure correct mesh with your chosen ratio.

Is aluminium stronger than plastic pulleys?

7075 aluminium provides higher hardness and less deformation under load than typical plastics, which helps maintain gear engagement and reduce wear over time.

How do I check pulley alignment after fitment?

After fitting, rotate the drivetrain while observing mesh and listen for roughness; use shims or adjust pinion depth if you notice uneven contact or binding.
