Mugen MRX5 Joint Shaft Upgrade Arrowmax AM-MRX5-H0273  [AM-MRX5-H0273]

Upgrade your Mugen MRX5 driveline with spring steel shafts

The Arrowmax AM-MRX5-H0273 joint shaft is purpose-built for the Mugen MRX5, using spring steel to balance durability and weight savings. This combination helps the chassis maintain consistent handling through extended sessions.

Smoother torque transfer and less wear

High-precision manufacturing produces shafts that reduce vibration and unwanted movement in the driveline, lowering the chance of accelerated wear on gears and bearings. These are a sensible enhancement for club racers and weekend drivers.

Simple swap-in replacement

These joint shafts are made for plug-and-play fitment on the Mugen MRX5, simplifying upgrades and repairs. Their robust build also reduces the frequency of part replacements during normal use.
