For the entire RB6 line up- 6, 6.6, buggy or truck.
Ultra light top shaft that has been drilled and the teeth narrowed for increased acceleration and a cooler running motor.
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.
Less than half the weight of the stock top shaft and slipper and lighter still than our standard spur mount set, when combined with our special lightened spur mount #1725, sold separately.
Only 10gr complete with hardware and 72 spur- the stock assembly is 20gr! Use optional alloy hardware for even more weight savings.
Compatible with the entire RB6 series but recommended for stock use only.
Hard anodized 7075 alloy.
REQUIRES EXOTEK SPUR MOUNT 1726, sold separately.
Extremely light weight
Less rotating mass
You cannot use a slipper on the top shaft
Must use Exotek or Kimbrough spur gears- can be seen as a positive :)
