One of the first parts to go in F1 racing is the spur gear. Exotek Racing now offers the stock 64P 86T spur gear individually as a replacement part.
This gear has 12 inner diff ball holes, allowing the use of all 12 balls (not all spur gears include that many). The more balls, the smoother the diff will be, so it’s a good idea to replace the gear with another Exotek gear.
