The XRAY 308164 XLP Spring Set gives model racers a progressive spring option tailored to the X4F 2023 chassis. With compression values from C=2.4 up to 2.7, these springs let you tune soak and rebound transition to suit different track grip levels. They are designed to offer repeatable behaviour session after session for club racing and hobby use.
These progressive-rate springs soften at initial travel and firm up deeper into the stroke, helping control roll and reduce sudden weight transfer. That progressive curve helps maintain traction through entry and mid-corner phases while resisting harsh bottoming on big bumps.
Designed specifically for the XRAY X4F 2023, the 308164 springs fit the original dampers directly. For best results, test one incremental change at a time and log results so you can recreate preferred settings for different track conditions.
