The XRAY 308264 Progressive 4S Spring Set gives your RC car a graduated response during cornering to improve stability and traction. These 20mm springs are specifically made for SLP shocks and aim to help drivers dial in corner speed.
At light compression the springs act like a C2.5 to increase front-end bite on entry. As the car loads up through the turn the spring rate steps up toward a C2.8 characteristic, smoothing the transition and supporting higher mid-corner velocity.
XRAY hand measures and selects each spring pair to ensure matched length and consistent damping traits. This hands-on quality control helps reduce setup surprises and keeps handling repeatable session to session.
