These are all of our Rod End Kits and they are a screaming deal. They all start with our 4130 CroMo Heat treated Heim Joints. Misalignment, Bungs, and Jam Nuts are added to make them a package and they come in pairs. Check in the Rod End Parts section for all the individual Rod Ends and the parts in the kits. We only recommend Tri Flow to service these joints, use of other products such as WD-40 or Blaster is never recommended and will void any warranty.
