Mugen MRX5 Rear Lower Shaft TiN Spring Steel Upgrade - Arrowmax AM-MRX5-D0104R  [AM-MRX5-D0104R]

Durable rear lower shaft for MRX5

Designed for RC Mugen MRX5 rear suspension assemblies, this rear lower suspension shaft is supplied as a 2 piece set. Made from spring steel with a titanium nitride finish, the shaft lowers contact friction and resists wear where it sits inside the lower suspension mount.

Functioning as a pivot and retention pin in the rear suspension, the component keeps linkages correctly aligned and provides a tough bearing surface for repeated movement. The TiN coating reduces metal-on-metal contact compared with bare steel, helping nearby components survive regular track use and maintenance cycles.

Installation notes: the shaft installs into MRX5 rear lower suspension mounts without modification and is suitable for rebuilds or replacing worn lower shaft hardware. Always confirm fit and secure fastening when reinstalling to preserve suspension geometry.
