If you want to refine your XRAY X4F 2023 handling, the XRAY 308166 Progressive XLP Spring Set offers a C=2.6-2.9 profile that improves responsiveness and gives smoother transitions through corners.
These springs provide a changing rate as they compress, which smooths small inputs and resists larger loads, helping maintain traction and predictable rotation on mixed surfaces.
Built for the XRAY X4F 2023 chassis, the springs fit directly and are simple to install. They are a practical upgrade for racers seeking more control without major chassis changes.
