Mugen MRX5 Front Upper Arm Pivot Shaft Upgrade - Arrowmax AM-MRX5-H2106  [AM-MRX5-H2106]

Front upper arm pivot shaft for the MRX5

This Arrowmax upgrade shaft is made specifically for the Mugen MRX5 front suspension. Constructed from spring steel and treated with a titanium nitride surface, the shaft aims to reduce friction at pivots and increase resistance to wear in active suspension link points.

Fit this shaft when replacing tired pivot pins or during a front-end rebuild to maintain correct steering geometry. The package contains 2 pieces to service both left and right front upper arms on the MRX5 layout.

Fitting tips: reuse the original chassis clips or pins where possible, ensure the arm moves freely through its full travel, and inspect for any binding after tightening. The coated finish is compatible with common RC greases and light oils used on pivot areas.
