Jimmy Joint Information:

Designed and manufactured at Summit Machine, the Jimmy Joint is the first rebuildable joint to perform like a heim joint. The high misalignment design provides 60 degrees of total misalignment. 30 degrees more than the Flex Joint. The Jimmy Joint is extremely durable. Each body is machined from a solid piece of heat treated 4140 steel. They are then plated with black zinc for superior corrosion resistance and a unique look. The pivot ball is machined from 303 stainless steel and carefully inspected for proper size and roundness. Races are precision molded from bearing grade Nylatron® GS.
