XRay XB2 and XB4 Spares List: Parts used in both cars

XRay XB2 and XB4 Shared Parts List

If you race both the XRay XB2 and XRay XB4, you've probably already noticed something:

Many parts are shared between the two platforms.

That's one of the biggest advantages of XRay's current 2WD and 4WD competition buggies. From bearings and hardware to suspension, shocks and drivetrain components, a large number of spares fit both cars.

Whether you race 2WD one week and 4WD the next, or own both cars, carrying shared spares means fewer duplicate parts, a lighter pit box and faster repairs at the track.

Why Shared Spares Matter

Keeping a stock of shared parts offers several benefits:

  • Smaller, lighter pit box
  • Fewer duplicate spare parts to buy
  • Faster repairs between rounds
  • Better value when ordering spares
  • Ideal for racers running both 2WD and 4WD

If you regularly race club meetings or BRCA regionals, these are some of the first parts worth keeping in your spares box.
