Mugen MRX5 Front Upper Arm Shaft - Arrowmax AM-MRX5-H2106 (2pc)  [AM-MRX5-H2106]

Front upper arm shaft for MRX5 applications

This Arrowmax option component is designed for the Mugen MRX5 front upper arm pivot. Built from spring steel and coated with titanium nitride, the shaft reduces friction at bearings and bushings while improving wear resistance in the front suspension links.

Use the shaft when replacing aged pivot parts or during a front-end rebuild to preserve accurate steering geometry. The part comes as a set of 2 to fit both sides of the MRX5 front upper arms.

Fitting guidance: install with the original retaining clips or pins from the chassis, ensure free movement through the arm's range of travel, and inspect for any binding after assembly. The coated finish remains compatible with usual RC greases and light oils applied to pivot areas.
