XRAY RX8 Hollow Front Shaft Upgrade - Arrowmax AM-RX8-345710 Spring Steel  [AM-RX8-345710]

Aftermarket front middle shaft for RX8 drivetrains

The Arrowmax AM-RX8-345710 front middle shaft is offered as a spare for XRAY RX8 scale touring cars and uses a hollow spring steel construction. It is positioned as an aftermarket option to the kit shaft, combining a lighter rotating profile with claimed toughness.

Role in the drivetrain: this shaft is designed to sit in the RX8 front driveline where a middle shaft transfers power toward the front assemblies. In tuning terms, moving to a hollow spring steel shaft usually trims rotating mass while keeping needed torsional rigidity, which can positively affect throttle response and reduce load spikes on front drivetrain parts.

Installation guidance: the item is supplied as the shaft only so verify any retaining clips or orientation details from your RX8 kit during installation, and inspect spline and seating areas for wear before use. Claims about durability and mass savings should be confirmed during bench testing.

Practical summary: the AM-RX8-345710 supplies a hollow spring steel alternative for XRAY RX8 front drivetrains that targets lower rotating mass with maintained stiffness; always trial-fit and validate performance before competitive running.
