Overview: New turbine cooling triple RC slipper disks for the Losi 22S* RC car top shafts for quicker slipper cool downs before the next pass. Provides added consistency due to 3 friction plates and slipper cooling via the extra heat sink fins that also spins as fan blades as the motor turns for increased air flow over the slipper plate therefore helping reduce heat glazing of the slipper pads which results in melted pads. * Not for the TLR22 series Features: RC slipper pads have a small 12mm inner slipper diameter for more surface area for improved slipper efficiency. Uses the stock RC slipper spring, and nut. Requires AE or EXOTEK Octalock spur gears (not included).
