These RuffStuff Specialties Chromoly Heims are a very high quality, “Heat and Cryogenically” Treated 4130 Chromoly Rod End!
The housing is machined from 4130 Chromoly and the Ball is made from 52100 Bearing Steel. Both are heat treated and hard chrome finished for improved strength and corrosion resistance.
The race is made from injection molded Teflon impregnated Nylon which is used between the two components to allow for smooth and precise ball movement.
This unique manufacturing process make these heim joints tougher than any other rod ends on the market! We can say it more than doubles their effective lifespan. Obviously they are priced a little more than a cheap mild steel heims… but that’s because the quality is worth it.
These rod ends are not tested to breaking point, but are tested to “first deformation point”. This is a key highlight point… deformation is NOT breaking point.
Several of the other companies making Rod Ends test to breaking point. You will stop using the heim joint after it has bent, so why even care at what point they fall into a pile of pieces on the ground. That just dosen’t make any sense to the end user.
We have a large range of sizes so you can find just the joint for your application.

More Information
Jam Nut
These rod ends come with Hex Jam Nuts. Right or left hand thread with 16 threads per inch.
Misalignment
Missalignment does 2 things necessary to run Rod Ends on a 3 or 4 Link Suspension.
The first and most important is allow additional room for the joint to pivot and let your suspension articulate. That comes simply from the shape of the missalignment.
The second and less important comes from a functional standpoint, but equal from the operational point of view as it serves as a spacer and reducer. This allows the use of a smaller bolt than the bore of the Heim.

Hello,
Thank you for your enquiry.
The rod end you need will depend on the size of the tube you will be using and if you are using the factory rod simply measure the size of the tube and then we can work out the most suitable size for your application. Below is a link to the ends we have available.
