For hobbyists tuning for sharper drive delivery, the XRAY 335582 hard springs are an effective upgrade. Intended for the #335540 Composite 2-Speed Gear Box Set, these springs increase the engagement threshold of the second gear for improved response at speed.
Designed to cope with the rigours of racing, these springs help the gear box maintain consistent operation under load. Raising the second gear engagement point assists with cleaner power transfer and crisper acceleration when it matters.
Whether you are tweaking your setup for a weekend event or carrying out maintenance, these hard springs are a straightforward way to refine gearbox behaviour. Their sturdy build helps reduce the frequency of replacements.
