RC builders wanting sharper engagement will find the XRAY 358585 hard clutch springs a solid upgrade. Crafted for higher stress use, these springs give increased tension and a later engagement point for improved control during competitive runs.
These XRAY springs are made to withstand regular racing loads and reduce the risk of fatigue failure. The stronger spring rate keeps the clutch engaging consistently, so you can tune throttle response more reliably across practice and race sessions.
Whether you are preparing a chassis for club racing or experimenting with different engine setups, the XRAY hard clutch springs offer a stable platform for setup work. Their resilience helps maintain predictable behaviour lap after lap.
