Mugen MRX-5 Rear Drive Shafts (Spring Steel) - Arrowmax AM-MRX5-H0291  [AM-MRX5-H0291]

Rear drive shafts made for MRX-5

This replacement pair of rear drive shafts is produced for the Mugen MRX-5 chassis and supplied as two pieces for axle rebuilds and routine maintenance. With spring steel construction, the shafts provide a blend of torsional give and longevity suited to race and practice environments.

Installation notes: fit one shaft on each side into the existing axle carrier and confirm clearance with the diff outdrive and wheel hub. Check spline engagement and secure retaining hardware to the correct torque. The component is intended as a direct-fit spare or hop-up for MRX-5 setups and will not change suspension geometry.

Tuning role: spring steel rear shafts help maintain straight-line stability under load and give predictable flex characteristics at corner exit, which is useful for drivers aiming for repeatable traction without the stiffness of hardened alternatives.

Use these shafts when refreshing the MRX-5 rear drivetrain to restore predictable handling; always inspect straightness and spline fit during installation to ensure dependable performance.
