XRAY 302134-XS X4 CFF Extra Soft Upper Arm Front/RL Performance  [XR-302134-XS]

Optimise Traction on Slick Surfaces for the XRAY X4

When track grip is limited, the XRAY 302134-XS CFF Upper Arm in extra soft is a solid tuning choice. Thinner carbon construction boosts mechanical and lateral traction, helping the car hook up on low traction carpet and asphalt.

Engineered for Controlled Steering

The arm contours around the inner shock position to maintain clearance without sacrificing necessary stiffness. That form improves steering precision and enhances both forward drive and side grip. CFF construction reduces radial play for repeatable handling.

Compatibility and Durability Notes

This arm fits front right and rear left locations on the XRAY X4 and excels on very low grip layouts, but keep in mind the softer material has reduced impact resistance compared to harder arms.
