In the world of ultra competitive stock racing at indoor tracks, every gram counts, and there is no better way to separate yourself from the pack than having a more efficient and lighter drive train.

Exotek spur mount assembly with 69t spur (sold seperately) is only 8.5gr (stock slipper assembly and spur is 20gr) and you could lighten it further by using optional aluminum hardware.


  • Works with all 3 gear box types.
  • Uses a wider range of available spur gear sizes by Exotek and Kimbrough.
  • Allows for easy switching between a locked spur or slipper as track conditions warrant.
  • Uses the stock top shaft for increased idler gear durability compared to narrowed top shafts.
