MUGEN MRX-5 Rear Upper Suspension Shaft Set (Spring Steel) AM-MRX5-J0105U by Arrowmax  [AM-MRX5-J0105U]

Rear upper suspension shaft for MUGEN MRX-5

This Arrowmax rear upper suspension shaft is made for the MUGEN MRX-5 chassis and carries model number AM-MRX5-J0105U. The shafts are manufactured from spring steel and finished with a titanium nitride coating to reduce surface friction and enhance wear resistance over standard components.

They function as pivot and load-bearing points within the rear suspension, helping preserve suspension geometry and limiting play at mounting points. The TiN finish reduces contact friction with bushings and bearings, aiding smoother suspension articulation and more repeatable handling during tuning and race use.

Installation is straightforward for anyone familiar with RC servicing: remove the original rear upper shafts, inspect adjoining bushings and bearings for wear, then fit the Arrowmax replacements. Regular hand tools are sufficient, and it is sensible to recheck alignment and fastener torque after initial runs to confirm secure seating.

Pack contents: 2 pcs rear upper suspension shafts supplied as a matched left and right set for the MRX-5 rear assembly.
