Track-focused hobbyists looking to strengthen their Mugen MRX5 can fit the Arrowmax AM-MRX5-H0277 rear axle shafts as a durable upgrade. Built from hardened spring steel, these shafts resist wear under heavy loads and help keep drivetrain parts reliable during competitive running.
Spring steel is chosen for its resistance to bending and fatigue under repeated stress. These shafts are designed to deliver predictable behaviour on acceleration and corner exits, reducing the chance of failure in hard-use situations.
Manufactured to match the Mugen MRX5 rear geometry, the shafts install cleanly and maintain correct alignment. Use them to replace worn originals or to harden a setup for club races and practice sessions.
