Overview
Eliminate your differential and unlock maximum drive on your Traxxas Slash, Rustler, or Stampede with the Hot Racing Locked Differential Hub Spool. This optional gearbox spool replaces the factory differential gears with a precision-machined locked unit, sending 100% of the motor's torque to both wheels for stronger acceleration, better climbing, and more aggressive on-power performance.
Built with a CNC-machined 6061 aluminum lightweight gear hub and a precision-ground stainless steel output shaft, this spool is engineered for the toughness Traxxas drivers demand. Hot Racing's center-less grinding process delivers a level of shaft refinement and hardness that translates directly into longer service life and smoother power delivery.
