XRAY 358334 85mm Rear Spring Pair Dual Dot - Vintage XB Setup  [XR-358334]

Track-tuned XRAY rear springs

For drivers who want sharper feedback and steadier cornering, the XRAY 358334 rear springs are a practical upgrade for older XB series machines. These 85mm springs are produced to deliver consistent behaviour so your car stays predictable across different track layouts.

Carefully matched for even damping

Each spring in the set is measured and paired to ensure nearly identical damping characteristics, helping to maintain balance and control while racing. The springs show a mild progressive rate that moves toward a more linear feel as they compress, aiding drivability on a variety of surfaces.
