Pinion Gear Information
All Sonic pinion gears, both press-on and solder-on are made to the same
high standard and from the same materials. Sonic cuts all their pinions individually on a
dedicated gear machine for maximum tooth precision. All types of slot cars
will get the same consistent high performance from all Sonic pinions.
