The Exotek F1 Spool with 1/4" Carbon Axle & Right Hub is an optional high performance upgrade intended for the F1ULTRA, X1, Roche or most F1 vehicles that use a 1/4" axle setup. A spool style axle helps to eliminate "diffing out" on high grip carpet conditions and offers more corner exit speed. Constructed with high quality 7075 aluminum this spool eliminates any holes in the axle shaft for increased durability over other setups. The Spur mount keys directly into the supplied right side wheel clamp and makes for easier gear swaps as well. Also the right side wheel clamp uses a 2 screw style clamping setup which requires less force on the screws for better clamping force. 

  • Requires a standard pan car ball diff type spur gear (Kimbrough, Axon etc)- not included. 
  • Also requires a left side clamping hub. You can use your stock hub for the F1ULTRA.


  • (1) Carbon Fiber 1/4" axle
