XRay Gear Differential 1:10 Formula - Set

The XRAY Gear Differential 1/10 Formula Set (XR374901) is a self-designed, super-smooth alternative to a ball differential, created specifically for 1/10 formula cars. It is a direct replacement that requires no extra parts and no additional adjustments, delivering stable, predictable handling with increased on-power steering. Especially in high-traction conditions, this gear diff makes the car easier to drive and more consistent across runs.

Engineered for longevity and minimal upkeep, the unit is effectively maintenance-free when correctly built. Thanks to a superior sealing system, it resists leakage and does not demand frequent oil changes, helping you focus on driving rather than servicing.

Performance Notes

Due to the nature of gear differentials and the forces involved, units used with both aluminium and graphite axles may be less resistant to wear and/or breakage than standard ball differentials. If reliability and lifetime are prioritised over outright performance, the standard ball differential is suggested.
