Improved mechanical grip with a soft upper arm

The XRAY 302144-S - X4 Soft Upper Arm for Inner Shock Position aims to improve steering accuracy and side traction for X4 chassis users. Manufactured from Carbon Fiber Fusion (CFF), it offers a compliant feel that helps the tyres maintain grip on slick circuits.

Optimised placement and handling benefits

This soft arm fits the front left and rear right positions to increase lateral stability and boost side bite on low-grip asphalt or carpet. Users should be aware that the softer material trades some durability for improved traction under moderate conditions.

Specifications

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

For competitive drivers seeking extra side traction and a sharper steering feel on low-grip tracks, the XRAY 302144-S soft upper arm is a targeted upgrade for the X4 platform.
Remark :

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 work with stock shocks and springs?

Yes, it will fit with stock shocks and springs, but you may want to retune damping to match the increased compliance and maintain predictable handling.

How does this soft arm affect tyre wear?

By improving mechanical grip and stabilising contact patch, it can change wear patterns; monitor tyres and adjust camber or toe to optimise longevity.

Are there simple upgrades to complement this arm?

Complementary changes include softer front or rear springs, revised shock oil, or small toe/camber tweaks to fully exploit the extra mechanical traction.
