The XRAY 308290 4S Spring Set provides consistent spring rate for precise chassis control. With a C=3.0 rating and a 20mm free length, these springs are suitable for tuners aiming for predictable roll and rebound behaviour on compatible SLP shocks.
Springs are matched for length and feel to reduce variance between left and right. This level of control helps keep lap times consistent and makes setup changes more repeatable.
The package includes two springs, offering an easy swap for replacing worn coils or experimenting with a different spring rate during race day adjustments.
