Differential Balls

For almost 20 years we have been on the cutting edge of RC differential ball technology.  From our original super strong Tungsten Carbide differential balls to our superlite HCCA ultralite differential balls all our balls are known for their smoothness, hardness, lightness and consistent concentricity.

We pioneered lightweight differential ball technology with the introduction of our world famous Ceramic Nitride pro series differential balls .  At 79% lighter than tungsten carbide, these ceramic balls, made from pure silicon nitride, allowed racers to tear up tracks with unprecedented lap times due to significantly lower rotational mass in their differentials without sacrificing hardness or durability.  In fact, our Ceramic Nitride pro series differential balls outlast even tungsten carbide .  That's why we became instantly known as "the hardest balls in the industry."
Try a fresh set of our differential balls in your differential today and see the results for yourself.  We have also added four new sizes for hardcore bicycle racing: 1/4" Silicon Nitride balls, 3/16" Silicon Nitride balls, 5/16" Silicon Nitride balls and 7/32" Silicon Nitride balls.
