Carli's ball joints start out as a chunk of specialty chosen material which is machined to Carli's unique design and then heat treated to a specified rockwell (hardness). From there the ball joints head to an aero-space lube company where a proprietary dry-lube coating is applied to their specified thickness. Carli tops them off with an accessible zerk fitting for easy servicing, plus they even include a tube of high quality synthetic grease with each ball joint set.
