Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this fit other XRAY rear arm configurations?

This shaft is specified for use with XB4 rear arms on the XB2 chassis. Other rear arm setups may require different shaft lengths or pin sizes, so check fitment before installing.

How does HUDY Spring Steel affect longevity?

HUDY Spring Steel is processed for high fatigue resistance and consistent hardness, which reduces wear and the likelihood of bending under hard use compared to softer steels.

Do I need to change other drivetrain parts when upgrading?

Upgrading the rear shaft is often paired with checking the ball differential, driveshafts and outdrives for wear. Matching components in good condition ensures the new shaft performs as intended.
