Sharper turn in with a soft XRAY upper arm

The XRAY 302144-S - X4 Soft Upper Arm for Inner Shock Position improves turn-in and overall mechanical grip for X4 chassis users. Constructed from Carbon Fiber Fusion (CFF), the arm provides a controlled flex that helps the tyre maintain contact when grip is scarce.

Geometry and material tuned for grip

This component is specified for the front left and rear right mounting points, delivering added lateral stability and improved side traction on asphalt and carpet. While the softer composition benefits handling on low-grip surfaces, it will wear faster than harder arms if subjected to heavy impacts.

Specifications

  • Material: Carbon Fiber Fusion (CFF)
  • Position: Front Left / Rear Right
  • Hardness: Soft
  • Compatibility: XRAY X4 Series

For drivers aiming to increase side grip and sharpen steering on low-traction layouts, the XRAY 302144-S soft upper arm is a targeted upgrade for the X4 range.
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 surface types benefit most from this arm?

Low-traction asphalt and short-pile carpet see the biggest gains, as the softer arm boosts lateral traction and tyre contact during cornering.

Will the arm fit older X4 variants?

It is designed for the XRAY X4 series. Fitment on older or modified X4 variants should be checked against existing mounting points before installation.

Should I adjust shock settings when I fit this arm?

You may need to soften damping or tweak rebound to match the extra compliance, as the arm changes suspension kinematics and weight transfer.

How can I tell when to replace the arm?

Look for visible cracks, deformed mounting holes, or a noticeable loss of steering precision; those are signs to swap in a new arm.
