From Exotek Racing:
Also works with Associated B5 based cars.
Our ultralight direct spur gear mount for the DR10 is here!
Machined alloy unit that weighs only 3.4gr with the screws.
Uses a wider range of available spur gear sizes by Exotek, Kimbrough, etc.
Allows for easy switching between a locked spur or the stock slipper slipper as track conditions warrant.
Uses the stock top shaft.
Some compatible spur gears:
EXO1545 75 tooth
EXO1546 78 tooth
