XRAY RX8 Front Middle Shaft Replacement - Arrowmax AM-RX8-345710 (Spring Steel)  [AM-RX8-345710]

Replacement front middle shaft for XRAY RX8

This Arrowmax AM-RX8-345710 front middle shaft serves as a spare for XRAY RX8 touring cars and is manufactured in a hollow form from spring steel. The part is presented as an alternative to the original kit shaft, aiming to balance lower mass with long-term strength.

Intended location and function: the shaft fits the RX8 front driveline where the middle/front shaft transfers torque through the front section. In practical RC tuning a hollow spring steel shaft tends to cut rotating mass versus a comparable solid shaft while retaining torsional stiffness, which can sharpen acceleration feel and preserve front driveline integrity under load.

Fitment and installation: the component is sold as the shaft only, so verify orientation and any retaining hardware from your RX8 kit when performing the swap, and examine spline seats for wear during installation. Manufacturer notes claim improved durability and mass reduction compared with the kit item; validate these on your bench prior to track sessions.

Summary: the AM-RX8-345710 is a hollow spring steel option for the XRAY RX8 front driveline that targets a trade-off between reduced rotating mass and component longevity; test fit and performance compared to the kit shaft before relying on it in competition.
