Precision Rear Arm for Tuned Handling

The XRAY 363123-H Hard Composite Rear Left Suspension Arm is crafted for drivers who want firmer control and longer-lasting parts. Compatible with the XB4 2020 Specs, this arm brings a longer profile and stronger material to refine rear-end behaviour.

Longer Profile for Better Rear Grip

Extended by 2mm over the stock arm, this component helps the rear wheels find more traction in lower-grip situations while remaining stable on tackier tracks. The design allows alternate shock mounting positions so you can alter roll and traction characteristics quickly.

Engineered Composite for Strength and Feel

Built from a specialist composite, the XRAY 363123-H aims to balance rigidity and impact resistance for predictable steering feedback. Its durable makeup stands up to frequent racing on medium- and high-traction circuits.

Fitment Notes and Setup Choices

This arm is specifically intended for the XB4 2020 Specs and must be used with the corresponding #363113-H hard lower right arm. The rear shock can be mounted either in front of or behind the rear shock tower to suit driving style and track conditions.
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.

Can I use stock shocks with this arm?

Yes, standard rear shocks will work; the important tuning lever is the shock position, which changes roll centre and traction response.

Is the XRAY 363123-H more brittle than standard arms?

The hard composite is stiffer and designed for durability under racing loads, offering a firmer feel rather than brittle failure when used within normal racing conditions.

Do I need to change other parts when fitting this arm?

No mandatory changes are required, but pairing it with the matching #363113-H hard lower right arm is necessary for correct geometry and reliable performance.
