The new RC4WD matched spur and pinion gears are here.

This set is considered a “Speed Set” because there is one more tooth on the pinion and one tooth removed on the spur gear - creating more speed on the top end with no modification to the engine.

Just pop them in and go!

The stock gearing is 17 tooth pinion and 57 tooth spur.

This set is 18T and 56T and is made of solid machined steel.

Use this set when you are looking for improved top speed.
