Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How do I set the correct shim stack for my clutch?

Start with the supplied shim combinations and adjust in small steps until the clutch engages smoothly without slipping under full throttle; track testing helps identify the best stack.

Can I use these pinions with electric conversions?

While intended for nitro/gas clutch systems, the pinion gears and bell may be reused in some electric conversions if the shaft and mounting dimensions match; verify fit before adapting parts.

What signs indicate the clutch needs service?

Look for uneven engagement, noisy bearings, or visible damage to the hard coat; regular inspection after race meetings helps catch wear early.

Are replacement flyweights available separately?

Replacement flyweights and individual clutch components are often available from parts suppliers; check your vendor for compatible XRAY flyweight spares.
