For hobbyists who tune for consistent lap times, the XRAY 338090 3S Spring Set provides a clear improvement in setup control. Made with RX Series compatibility in mind, these springs are produced to offer dependable handling. The kit contains two springs that are measured and matched to ensure identical length and damping, which helps reduce setup guesswork on older vehicles.
The XRAY 338090 3S Spring Set is created to complement LP shocks and sharpen mid-corner steering. Equalised front and rear spring lengths simplify tuning choices and help the vehicle respond more predictably to driver inputs, especially when refining balance for different track surfaces.
Each spring is hand-measured and selected to provide consistent performance across the pair. That level of quality control supports predictable damping and balance between runs. Whether refreshing a classic racer or seeking tighter handling, these springs help maintain a steady setup baseline.
