12mm to 17mm Wheel Hex Hub Adapter for 1/10 RC Cars – CNC Aluminum Conversion Set

This 12mm to 17mm wheel hex hub adapter lets you mount 1/8 scale 17mm hex wheels on many 1/10 scale RC cars that come with factory 12mm hex hubs. The set includes four CNC-machined aluminum adapters, four 5mm bolts, and four screw caps. Each adapter is 24mm long, accepts a 4mm axle screw, and has a max axle diameter of 5mm. The titanium-colored anodized finish adds a clean look while the billet aluminum construction keeps the set lightweight at 48g total. Note: these adapters are not compatible with 2WD models that use bearings instead of 12mm hex hubs.

Are these adapters compatible with my 1/10 RC car?

These adapters work with many 1/10 scale vehicles that have factory 12mm hex hubs. They are designed for 4mm axle screws. If your model uses bearings instead of 12mm hex hubs (common on some 2WD cars), these will not fit. Check your car’s hub type before purchasing.

Frequently asked questions

Will these fit Traxxas or Arrma 1/10 models?

They fit any 1/10 scale model that uses factory 12mm hex hubs and a 4mm axle screw. Always verify your vehicle's hub type before ordering.

Can I use these on 1/8 scale cars?

These adapters are sized for 1/10 scale cars; they are not intended for 1/8 scale vehicles.

Do I need to ream the wheel hex to 17mm?

No, the adapter converts your 12mm hub to a 17mm hex, so wheels with 17mm hex openings mount directly.
