ProTek RC 3/32" (2.4mm) Tungsten Carbide Differential Balls (14) PTK-2025

This is a package of fourteen ProTek R/C Tungsten Carbide Differential Balls, the perfect upgrade for ball differentials. These high-quality balls can be used with any ball differential requiring a 3/32" (2.4mm) ball.  PTK-2025 When it comes to diff balls, there are three main materials to choose from: steel, ceramic and tungsten carbide. While steel balls are included with most ball differentials as standard equipment, they provide the shortest life span. Ceramic diff balls on the other hand are the smoothest, but can sometimes leave the diff slipping and feeling like it can't be tightened enough. The third material, Tungsten Carbide, is the happy medium of the three. Why Tungsten Carbide? Tungsten Carbide is an extremely hard material, composed of equal parts tungsten and carbon atoms. Compared to steel, it is nearly twice as stiff and much denser. It also features great resistance to heat making it a great solution for cutting tools, machinery, drill bits and especially R/C diff b
