If you were a Tamiya Clod Buster fan back in the day there were few companies that made durable hop up parts for you truck but JPS was always there supplying the hobbyists with what they needed. This advertisement was for their bullet proof steel Clod Buster gears. If you were into truck pulling these were a must have! JPS also made aluminum axle tubes, gear housing, wheels, an awesome chassis and more! We also have tons of Vintage RC Car Ads in our RC Car Pictures Gallery. Go check them out!
