Fine-Tuned Steering with XRAY 302134-S Carbon Upper Arm

The XRAY 302134-S X4 CFF Upper Arm soft version sharpens steering response and increases lateral grip for racing on low-traction asphalt and carpet. It fits the front right and rear left positions, making it a direct upgrade for racers chasing precise handling.

Carbon CFF Construction and Fit

Made from CFF (Carbon Fiber Fusion), this upper arm balances light weight with stiffness to support precise steering inputs. The profile maintains clearance around the inner shock while preserving strength to aid both forward and side traction. Note that the softer compound increases mechanical grip but is more prone to damage than firmer options.

Built for Low-Grip Surfaces

Recommended for very low to low traction tracks, the soft upper arm reduces radial play and helps the tyres track truer through corners. The result is improved control where side traction makes the biggest difference.
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 arm fit older X4 chassis versions?

It fits X4 series models that use the same upper arm mounting layout; double-check your chassis layout before purchasing.

How does soft compare to hard arm in handling?

Soft arms increase mechanical grip and side traction, making the car easier to rotate on slick surfaces, but they can wear or crack faster under heavy impacts.

Any setup tips when fitting this arm?

Try starting with small toe and camber adjustments and test on carpet or low-grip asphalt to find the balance between steering precision and tyre wear.
