Sealed ball bearings for XRAY NT1 chassis upgrades

Owners who want tighter drivetrain response can fit the XRAY 339000 NT1 High-Speed Ball Bearings Set, which contains 24 bearings matched to NT1 positions. Precision sealing helps keep contaminants out and supports reliable rotation under load.

What the kit covers on your NT1

The set supplies bearings for clutch assemblies, belt tensioning points and primary drivetrain bearings. Rubber-sealed high-speed bearings reduce ingress and help maintain consistent lap times with less frequent strip-downs.

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.

Do these fit directly onto NT1 shafts?

Yes, the sizes match NT1 factory bearing locations. Verify each bearing size against the part layout before final assembly.

Will sealed bearings slow the car down?

Properly selected sealed high-speed bearings usually reduce overall drag by keeping contaminants out and preserving rolling quality, so they tend to help lap times rather than hurt them.

What track conditions are these best for?

They perform well on clean asphalt and carpet. On very dusty or wet circuits, inspect and clean more often despite the seals to avoid premature wear.
