If you want crisper gear changes, the XRAY 335582 hard springs are a targeted upgrade. Intended for use with the #335540 Composite 2-Speed Gear Box Set, these springs raise the engagement position of the second gear to enhance responsiveness at higher speeds.
These springs are specified to cope with demanding use and help the gearbox remain stable under load. The increased engagement point supports steadier power transfer and improved acceleration for precise driving control.
For fine-tuning on the bench or routine servicing, these hard springs are a simple way to adjust gearbox behaviour. The durable design helps extend service life and reduces the need for frequent replacement parts.
