This is a pack of fourteen 3/32″ ceramic differential balls from ProTek R/C. These differential balls can be used to replace you steel, or carbide 3/32″ differential balls for smoother differential operation and longer service life. These are the same size as 2.4mm differential balls used in cars like the XRAY T2 family.
Why Ceramic?
Our ProTek Ceramic Differential Balls are made from Si3N4 silicone nitride ceramic. Ceramic differential balls have many advantages over standard steel balls, such as decreased weight, higher RPM capabilities, increased corrosion and wear resistance, as well as reduced friction and vibration.
So next time you purchase differential balls, when you ask yourself “Why should I buy Ceramic?” You should be asking yourself “Why shouldn’t I?”
Advantages of Ceramic:
- High Speed: Ceramic differential balls can reach a resistance level of 1,200,000dN with grease lubrication, due to reduced slip, wear extent and heat productivity.
- Lightweight:The weight of ceramics is 60% lighter than steel, which decreases the centrifugal force and overall weight.
- Long Service Life:The service life of ceramic balls is 3 to 5 times longer than that of steel in comparable working conditions.
- Self Lubricating: Even when poorly lubricated or with no lubrication, ceramic differential balls will continue to function longer than steel under the same level of stress due to their self lubricating properties.
- Corrosion Resistance:Ceramic differential balls have excellent corrosion resistance, and will continue to function while corroded.
- High Rigidity:The elastic ration of ceramics is 1.5 times greater than that of steel, this dramatically increases the rigidity of the balls.
- Low Friction:Ceramic materials have a low friction force. Even under the conditions of boundary lubrication, the surfaces are extremely smooth, so its friction force is low and the rotational friction moment is low.
- Wear Resistant:The micro-hardness of ceramics can reach a Vickers Hardness level of HV1700 kg/mm2, which dramatically increases the wear-resistance.
ProTek R/C also offers 3/32″ Tungsten Carbide Differential Balls (PTK-2025).
Note: Some ball differentials require 12 balls, others require 14. This package contains 14 diff balls to service both. If your diff requires only 12 balls, you will have two unused balls remaining.

Matthew Gosch Thursday, Aug 28 2014 (about 11 years ago) ProTek RC 3/32″ (2.4mm) Ceramic Differential Balls (14) Want your diff to last twice as long as it does now? Try these ceramic diff balls from ProTek. I use them in all of my 1/10 vehicles and can easily go months without a diff change or adjustment. They now contain 14 balls for the newer style of 1/10 vehicles. 1 of 2 customers found this review helpful. Daniel Bender Verified Owner Wednesday, Aug 10 2022 (about 3 years ago) ProTek RC 3/32″ (2.4mm) Ceramic Differential Balls (14) One of the balls came flat now I will have to replace the diff again and get new diff balls not getting protek ceramic balls again. 0 of 1 customers found this review helpful.
