Rear-End Stability Upgrade

The XRAY 363113-H hard rear right arm is made to sharpen rear traction and improve stability across common race surfaces. Its long, stiff composite profile is aimed at drivers chasing consistent lap times on medium- and high-traction tracks.

Extended Arm Length for Improved Bite

This revision is 2mm longer than previous arms, providing increased rear tyre engagement in lower-grip spots while keeping predictable behaviour on tackier surfaces. The firmer feel supports confident corner exits.

Shock Mount Versatility

The XRAY 363113-H allows shocks to be fitted either in front of or behind the rear shock tower, giving you setup options to influence roll centre and rear traction according to track demands.

Vehicle Fitment

Designed specifically for use on the XRAY XB4 2020 chassis. For best results pair it with the matching #363123-H hard lower left arm to maintain symmetrical handling balance.
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 arm affect corner entry?

Yes, the longer, stiffer arm can change front-to-rear balance; you may need to soften front or adjust anti-roll to keep desired turn-in behaviour.

Does it fit aftermarket uprights?

It is made for the XB4 2020 geometry; compatibility with aftermarket uprights depends on their dimensions. Check mount spacing and pivot height before fitting.

How should I set shocks after installation?

Start with small damping changes and test in a few laps. The arm often benefits from slight shock softening first, then tune rebound to control rear traction through bumps.
