Mugen MRX5 Rear Lower Suspension Pin Spring Steel TiN Finish - Arrowmax AM-MRX5-D0104R  [AM-MRX5-D0104R]

Rear lower pin built for MRX5 duty

This rear lower suspension shaft is produced for RC Mugen MRX5 rear suspension assemblies and is shipped as two pieces. Constructed from spring steel and coated with titanium nitride, the shaft is intended to lower contact friction and resist wear where it locates inside the lower mount.

In service the shaft serves as a pivot and retention element within the rear suspension, keeping linkages aligned and supplying a durable bearing surface under repeated movement. The titanium nitride layer reduces metal-to-metal friction compared with untreated steel, which helps protect adjacent parts during frequent running and maintenance.

Installation advice: the part fits MRX5 rear lower suspension mounts without alteration and is ideal for rebuilds or replacing worn lower shaft hardware. Verify correct seating and secure fastening after installation to keep suspension geometry accurate.
