Default Control arms with Johnny joints

A few years back I read a thread on installing Johnny joints in stock control arms
Now I can not find it. Does anyone remember this?

I’ve been thinking you could just machine a hiem joint down. Also started looking for smaller j-joints.

No cutting required then.

Thoughts anyone?

I see my old thread is still alive 👍

For the front arms I don't see a huge benefit using JohnnyJoints or Heim joints, the arms only move up and down and don't rotate like the rear trailing arms.
For the front a Heim joint would have to be screwed in so it's adjustable, that's the only benefit I see.... A threaded tube could be welded into the stock arms if you want it to be adjustable with the stock 'look'

benefit would be that the bushing would not melt.

I understand that the del-a-lum bushings will melt with the heat from the headers.

this is a big block car

Duntov sells this set up with the johnny joints but they are very proud of their parts.

why would they need to be adjustable, the thurst washers and lock nuts will hold it in place

like I said, there was a thread on this a few years ago, just can't find it

You are probably looking for this thread:

Not really sure I understand why poly joints will melt but Johnny Joints won't melt since J-Joints use poly (for the ball cups).

You could use spherical bearings, they won't melt.

I like the Howe bushings that mfain suggests. Not sure if they are spherical.

The smallest spherical bearings I’ve found were for g bodies.

Global West makes a spherical bushing kit, I use something very similar from Herb Adams on my racer, Global doesn`t advertise that they sell it separate but they do, click the link then click on the smaller pic.

Well ... If your front A-arm bushings are melting you have some other problems ... Lol
