If you know our history, you know our spurs. Often the most requested part we remake was our spur gears. Knowing a lot has changed since we last made spur gears we evaluated the changes the scale has endured over the last decade and came up with an all new spur. This spur is the lightest 53T spur you can currently buy, completely machined from a solid piece of Delrin which also makes it long lasting and super true. The design incorporates 9 holes for 3/32 balls (2.381mm) which gives you the option of running 9 or 6 balls.
We recommend 9 for super stock and modified and 6 for slower classes and low bite.
This spur is compatible with most Mini-Z type ball differentials, but they do require a separate 4x7x2mm bearing.
