universal flex joints heim joints

SPC's Sealed Flex Joints are essentially sealed heim joints which allow more rigid and precise articulation for increased performance and durability while also being protected from debris and the elements. These joints provide a great alternative to replace OE joints for vehicles built for racing or off-road.

SPC's xAxis features:

  • Grease retaining seal
  • Protection from contaminants
  • Electroless nickel plated ball for durability
  • 45 degree articulation
  • Common sizes for builders and racers

SPC has press adapters available for each xAxis joint for quick and easy removal of the old bushing and installation of your new joint. Receiver assemblies are available to allow replacement of original tie rod ends with xAxis Flex Joints.
