The Factory Pro FP-B-CDB312 set contains twelve 3mm ceramic differential balls engineered to improve drivetrain durability. Their ceramic finish lowers friction and stands up well to extended running compared with ordinary steel balls.
Ceramic balls resist surface wear and reduce heat from rolling friction, which helps keep diff parts in better shape during long runs on rough or mixed terrain. That makes them a sensible upgrade for off-roaders.
These 3mm ceramic balls are compatible with many common differential assemblies. Check your diff specifications and replace balls during a rebuild to maintain consistent gear engagement and performance.
