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

Aftermarket front middle shaft for the XRAY RX8

The Arrowmax AM-RX8-345710 front middle shaft is supplied as a spare for XRAY RX8 touring cars, fabricated in a hollow spring steel form. The item is offered as an aftermarket alternative to the stock shaft, focusing on reduced rotating inertia while retaining structural stiffness.

Functional overview: the shaft is used in the RX8 front driveline to relay torque through the front section of the drivetrain. From a tuning perspective, a hollow spring steel shaft can cut rotational mass relative to a solid equivalent while keeping torsional stiffness, which may improve throttle response and reduce stress on front driveline components in normal use.

Fitment advice: this product is sold as the shaft alone, so check your RX8 kit for the correct orientation and retaining parts before swapping, and inspect spline and seating regions for wear during fitment. Claims regarding durability and mass reduction should be verified on the bench prior to competition.

Conclusion: the AM-RX8-345710 is a hollow spring steel replacement for the XRAY RX8 front driveline aimed at those seeking a balance of lower rotating mass and component durability; always test fit and performance before race use.
