The XRAY 308290 4S Spring Set is aimed at builders who want stable, repeatable suspension behaviour. With a C=3.0 spring constant and 20mm length, the springs are sized for SLP shock applications and straightforward tuning swaps.
Each coil is measured and paired to ensure even free length and matching spring feel, helping to keep handling symmetrical and predictable during aggressive cornering.
This pack contains two springs, making it a direct replacement or a neat upgrade for hobbyists adjusting ride height and responsiveness.
