Currie Enterprises has an extensive line of Johnny Joints for use in myriad applications, but there are still some situations that call for something custom. In this case, we needed Johnny Joints with 7/8-inch fine thread shanks to match a set of existing Total Chaos suspension links.?>
Currie knows there’s a need for builder parts to match custom situations like this one, so Johnny Joints are also offered without threaded shanks. This lets the builder create custom suspension links, traction bars, Panhard rods, and so on. We’ve seen Johnny Joints used as tire carrier pivots. Your imagination is the only limitation. About the only place Johnny Joints aren’t ideal is in steering linkages, a situation that calls for the higher rigidity of Heim joints and conventional ball joints.
Back to our links. We’re using these custom Johnny Joints to replace an existing set of Heim joints. Why replace the Heims with Johnny Joints? Johnny Joints run quieter and last longer than Heims. Since Johnny Joints are a spherical steel center encased in urethane, they offer a degree of shock and vibration absorption over and above Heim joints, which are metal-on-metal separated by a Teflon liner. If you’re tough enough to wear out a Johnny Joint, replacement urethane inserts are readily available and inexpensive. Finally, Johnny Joints are greaseable for the smoothest-running, longest life possible.
