The Powergrid system has incorporated adjustable THK resin ball-stud links. You may recognize their fixed length siblings that are finding themselves on many new production vehicles. Their toughness is supported by laboratory and field durability testing to the stringent OEM requirements. Heim joints and high misalignment spherical bearings were considered, but do not offer the compliance, the waterproof seal, and are limited in their range of angular articulation. The ball links also offer a very low friction in the joint and has up to 50 degrees of articulation. This eliminates binding and allows for smooth load transitions.
