Fine tuning for older XB models

The XRAY 364183 spring provides a C=50 compression rate tailored to vintage XB slipper units. This black spring allows precise adjustment of clutch engagement so you can control wheelspin and protect gears in both practice and race use. It is a reliable spare for classic builds and ongoing maintenance.
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.

Is this spring a direct swap for original XB parts?

In most cases it fits the original XRAY XB slipper assemblies, but confirm the shaft and plate dimensions match your car before installing to ensure a direct swap.

When should I choose C=50 versus softer or stiffer springs?

Choose C=50 for a middle ground that reduces wheelhop while still allowing controlled slip. Softer springs suit low-grip surfaces, stiffer ones for heavy acceleration on grippy tracks.

Can this spring handle regular club racing use?

Yes, when installed correctly and inspected regularly, the spring holds up well for typical club and club-level race conditions. Replace if you see deformation or loss of tension.

Any installation tricks to get consistent engagement?

Use a small amount of light grease on contact faces, set initial preload conservatively, and test on-track to make small incremental changes rather than large ones.
