XRAY Carbon Fusion Upper Arm Design

The XRAY 302142-M X4 Carbon-Fiber Fusion Upper Arm blends a carbon backbone with a shaped composite body to create a consistent suspension link for racing. The fusion approach yields repeatable feedback lap after lap.

Precision Assembly and Flex Tuning

CFF arms are produced by bonding a carbon fiber plate inside a composite mould. The carbon plate thickness controls stiffness and bend behaviour, while the composite layer moderates rebound and keeps the arm predictable under load.

Minimal Weight, Maximum Control

Constructed from quality graphite and composite compounds, the XRAY 302142-M upper arm remains light and compact. The medium hardness rating suits a variety of track surfaces and is intended for front left and rear right mounting to tune 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.

What suspension setups benefit from using the XRAY 302142-M arm?

Medium hardness arms are a good compromise for drivers needing both steering bite and stability. They pair well with medium to soft springs and standard shock pistons for an even balance.

Are there recommended maintenance steps for carbon-fusion arms?

Keep pivot points clean and inspect for hairline cracks in the composite. Replace the arm if you notice delamination of the carbon layer or visible structural damage after repeated impacts.
