MUGEN MRX-5 High-Durability Joint Shaft (spring steel) - Arrowmax AM-MRX5-H0273  [AM-MRX5-H0273]

High-durability universal joint shaft

The Arrowmax AM-MRX5-H0273 joint shaft is an RC-scale replacement sold as a two-piece set, formed from spring steel to resist deformation under repeated motion. It is suitable for installation in MUGEN MRX-5 universal drive assemblies as an aftermarket replacement.

The shaft functions as the rotating pin inside universal joints, transferring loads and keeping the drive cups aligned. Spring steel improves resistance to bending and fatigue versus softer metals, helping the shaft preserve fit and operation during regular running.

Fitting is a direct swap into the universal assembly to replace worn or bent originals. Confirm the retaining method and seating used by the model before final assembly, then check that the joint rotates freely. The product is supplied as 2 pcs per pack for simple replacement on both drive sides.
