Mugen MRX-5 Rear Driveshaft Upgrade, Spring Steel - Arrowmax AM-MRX5-H0291  [AM-MRX5-H0291]

Replacement rear drives for MRX-5

These rear drive shafts are made specifically for the Mugen MRX-5 chassis and arrive as a pair to support axle rebuilds and upkeep. Built from spring steel, they aim to combine useful flex with lasting durability appropriate for racing and practice sessions.

Installation notes: place one shaft on each side into the existing axle carrier and confirm clearance with the differential outdrive and wheel hub. Check spline engagement carefully and secure any retaining hardware to the manufacturers torque values. This part is intended as a direct-fit spare or hop-up for MRX-5 layouts and will not alter suspension geometry.

Tuning role: using spring steel rear shafts helps retain straight-line stability under load and supplies predictable flex during corner exit, suited to drivers wanting steady traction response without the jump to very stiff alloys.

Replace MRX-5 rear shafts with this pair to restore consistent driveline behaviour; inspect each shaft for straightness and spline fit while installing to maintain dependable running.
