If you want longer service life and steadier differential action, the Arrowmax AM-200171 differential balls are an excellent upgrade. Made from high-grade carbide, these 1/8 inch spheres resist wear and help maintain reliable contact inside ball differentials.
These carbide balls suit hobbyists seeking tougher drivetrain parts that tolerate frequent running. They work with many setups that use 1/8 inch diff balls, making them a straightforward swap for compatible assemblies.
Before fitting the balls, clean the differential housing thoroughly and keep contaminants out. Use the lubricant recommended for your differential type, and perform routine inspections to preserve smooth operation.
