TSR "Black Balls" Ball Differential Full Rebuild / Upgrade Sets makes it easy to upgrade your differential for more durability and improved performance.   The set includes everything you need to make the rebuild process as seamless as possible. Si3N4 Silicone Nitride Differential Balls are manufactured out of a extra-hard Silicon Nitride Ceramic material, which significantly improves the differentials lifespan, increases RPM capabilities, provides increased corrosion and wear resistance as well as reducing friction, vibration and offering the capability of holding up to lighter differential settings better than standard steel or carbide balls. These Si3N4 ceramic differential balls can be used to replace both steel or carbide differential balls for smoother differential operation and longer service life.

PRO Spec sets include pure ceramic caged thrust bearings for increased performance and ease of maintenance.

At TSR, we race and understand the kind of discipline and commitment needed to win at the highest level. Time in the pits is time lost on the track and our goal is to keep you out of the pits and out on the track.
