The Exotek B6/B6D Flite Top Shaft is an ultra lightweight top shaft that has been drilled and the teeth narrowed for increased acceleration and a cooler running motor. Plus, its made in the USA! 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 lighter, more efficient drive train.

Less than half the weight of the stock top shaft and slipper and lighter still than the standard spur mount set. When combined with Exotek's special lightened spur mount (EXO1726 - must use & sold separately), the complete assembly weighs just 9.5 grams complete with hardware and 72 spur - the stock assembly is 22 grams! And, you can use aluminum or titanium hardware for even more weight savings!


  • Extremely light weight
  • Less rotating mass
  • Lower CG
  • You cannot use a slipper on the top shaft
  • Requires Exotek Spur Gear Mount EXO1726
  • Must use Exotek or Kimbrough spur gears
