Exotek 48P XB4 Center Gear Differential Spur Gear (74T) (Spec Racing)
This is an optional Exotek 48 Pitch, 74 Tooth XB4 Center Gear Differential Spur Gear. This spur gear is ideal for spec racing, such as 13.5t spec racing. For XB4 buggies equipped with the center differential - not slipper!
Allows you to gear higher thanks to the smaller tooth count, allowing you to run bigger pinions without cutting and modifying the stock motor plate.
Includes M2.5 hardware so that it reverse mounts to the spur while allowing the spur teeth to clear the hardware.
Heavy duty machined delrin for precision and durability.
NOTE: Not for the slipper set.

Seems to work fine with that note.)
I have since talked with Exotek who said you need to alter the motor mount so you can use a sunken screw head. Sent me pictures of a Dremeled motor mount plate. Cause that's what you do with $520 kits. And this is something they JUST noticed? Very disappointing.)
