Changing Rear Suspension

[Prslegmaker]

I like to have adjustability in any suspension system without needing to remove a Heim joint. I decided to modify the suspension arms on my 3 link and adding the ability to adjust it. It required cutting them and welding a 3/4-16 bung into place, then threading a longer piece of right hand 3/4-16 rod into the bung. I bonded it in place with coating the internal thread with JB Weld. I measured all of my initial piece in advance so I could get close afterwards. Using a Chromoly pipe, I welded the 3/4-16 LH and Right hand bungs into the pieces and welded them. Once installed, I have a truly adjustable setup, in case I ever choose the adjust it.

Great Idea. There is another item that could be used so that you do not have to bond the threaded rod and not have to turn the tube.

Makes suspension adjustments super easy. Put a right/left jam nut on each end and then yoy can use a wrench to adjust.

A simpler idea, but the way I did it required 3 of these and the rod I bought was the price of 1 of them. Thank you for showing me that as I know I will have other uses in the future.

The upper control arm on the three link has left hand threads on one end and right hand threads on the other end. You just have to loosen the jam nuts and twist the tube to lengthen or shorten the upper arm.

The lower control arms are forged aluminum and are a fixed length. You could build your own with the proper length tubes and hiem joints.

My upper arm only had the one set of threads which required me to take the bolt out of the hemi joint end and then rotate and put back in.
My lower arms were steel tubes with a ladder style reinforcement.
