Mugen MRX5 Rear lower suspension shaft (spring steel) by Arrowmax AM-MRX5-D0104R  [AM-MRX5-D0104R]

Rear lower suspension shaft for MRX5

This rear lower suspension shaft is made for RC scale Mugen MRX5 rear suspension assemblies, supplied as a set of 2 pcs. Manufactured from spring steel and finished with a titanium nitride coating, the shaft is intended to reduce contact friction and resist wear where it locates inside the lower suspension mount.

In practical use the shaft acts as a pivot/retention element in the rear suspension system, maintaining alignment of linkages and providing a durable bearing surface for repetitive movement. The titanium nitride surface reduces metal-to-metal friction compared with bare steel, which helps preserve surrounding parts during routine track use and maintenance cycles.

Installation notes: the part installs in the MRX5 rear lower suspension mounts without modification, and can be used during rebuilds or when replacing worn lower shaft hardware. Check fit and securement when reinstalling to preserve suspension geometry.
