MRX5 Thrust Bearing Retainer - MUGEN AM-MRX5-H0756 spring steel  [AM-MRX5-H0756]

Thrust retention piece for MRX5

This Arrowmax AM-MRX5-H0756 unit is an RC-scale thrust bearing stopper designed for MUGEN MRX5 applications, manufactured from spring steel to resist permanent deformation from repeated loading. It provides a compact axial stop that locates thrust bearings within the diff or transmission stack.

In practice the retainer helps preserve bearing face alignment and reduces unwanted axial movement that can upset gear mesh during acceleration or when negotiating corners. The item is aimed at hobby-grade 1/8 and 1/10 scale electric touring and racing models using the MRX5 family where a small thrust retention element is needed.

Installation follows normal differential service procedures: strip the differential, identify the thrust bearing position, then place the spring-steel stopper to achieve the intended preload and axial position before putting the assembly back together. Alter stack height and preload in small steps and verify gear alignment on the bench.
