1up Racing Precision Carbide Differential Balls are the perfect choice for racers seeking a buttery smooth ball diff for maximum grip and corner speed from their 2wd Buggy or Truck. Our Precision Carbide Balls measure within one 100,000th of an inch in diameter at all points ensuring each bears an equal load for improved forward traction and differential life. This precision gives you the smooth feel of a ceramic diff ball, with the perfect hardness and ease of setting that comes with a Tungsten Carbide Diff Ball, the best of both worlds!
Upgrade your diff's performance and lifespan even further with our Pro Ball Diff Grease Set!
