XRAY Hard Composite Arm for Tough Conditions

The XRAY 343131 Rear Upper Suspension Arm is manufactured from hard composite to strengthen rear suspension response and stability for GT and offroad track use. It performs reliably in hotter conditions and on high-grip surfaces.

Material Strength Explained

Hard composite parts resist bending under heavy loads and help maintain consistent suspension behaviour. The XRAY 343131 arm is a direct upgrade for racers seeking firmer rear support without changing chassis layout.

Handling Benefits on High Traction

On tacky surfaces the harder arm reduces flex, improving cornering stability and limiting mid-corner lift. This can help lap consistency during longer race runs.
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 using stock hardware?

In most cases the XRAY 343131 arm installs with the original pins and screws. Verify fit on your specific rear hub before final assembly.

How often should I inspect the arm?

Check for wear and cracking after heavy impacts or extended race use. Regular inspection keeps suspension performance predictable.

Do I need different spring rates?

A firmer rear arm can be paired with slightly softer or firmer springs depending on balance goals; tune by small increments and test on your track.
