MRX5 Thrust Stop Upgrade (spring steel) MUGEN AM-MRX5-H0756  [AM-MRX5-H0756]

Aftermarket thrust stop for MRX5

This Arrowmax AM-MRX5-H0756 piece is an RC-scale thrust bearing stopper made for MUGEN MRX5 platforms, supplied in spring steel to limit elastic deformation under repeated loading. It serves as a compact retention item that constrains axial movement of thrust bearings within the differential or transmission stack.

On the vehicle the stopper assists in maintaining bearing face alignment and cuts down unwanted axial play that can change gear mesh during heavy acceleration or when cornering hard. The part targets hobby-grade 1/8 and 1/10 scale electric touring and racing cars using the MRX5 chassis range where a dedicated thrust retention component is required.

Fitting follows standard differential servicing steps: remove the diff assembly, locate the thrust bearing area, fit the spring-steel stopper to set the desired preload and axial stop, then reassemble. Make incremental adjustments to stack height and bearing preload and check gear alignment on the bench.
