Four bar fabrication

I am ready to fab the bars for my rear four bar setup I am building and need to know where to get Polyurethane rod ends. Speedway motors has some real reasonable priced ones (part#91008051) but they say they have nylon bushings. All the nylon I have ever worked with is real hard, not what I want in my rod ends. Has anyone ever actually seen on of their rod ends? is it really nylon or is it polyurethane? Thanks!

I'm using the Speedway nylon ends on my current project. The nylon insert does have a slight bit of "flex" to it...although not much.

So they are fairly soft? I am building a triangulated four bar and am going to need some give. If you say they have a little give I bet they are polyurethane and not nylon.

Thanks

I have a few different sizes on my website www.*.com go into the online store, and go to fabrication parts. Page 5 I think.

I hope I didn't give you the wrong impression. I would not use the term "fairly soft" in describing these bushing just a bit of flex to them. It's sort of difficult to explain - certainly not the type of give you would get with a rubber bushing (like a Chevelle 4-link etc.). You might just want to order one from Speedway and check it out. Or if you want to just pay the postage I can send you a set of bushings and then you can mail 'em back to me after you've checked it out. PM me if you want to try that route.

I think I'll just order some up. I'm going to order four threaded rod ends and one set of replacement bushings (8 bushings). I'm going to leave one end of my rods solid and thread the other end. Are you using them for a four bar setup or something else?

I'm using them for a 4-bar (not triangulated) front and rear suspension. You can see what I've done with them by clicking on My Project Journal. Once there, the pics are probably around page 7 or 8.

If at all possible I would thread both ends of your rods instead of solid on one end. The ease of making "in place" adjustments is very handy. If one end is solid, you have to dis-assemble the bars to make any adjustments. If you tread at both ends (and in opposite directions) all you have to do is turn the bar to do your fine tuning.

Hey IAS you got any good discounts for a fellow Hot rodder menber? What are the dimensions of the "Tigged Rod End With 2 Poly Bushings, Sleeve & Jam Nut" thats on your website. And are they available with left handed threads? I'm having a hard time finding anything with 3/4" threads. There are a bunch with 5/8" threads, but I think the 3/4" ones will make me feel better.

Thanks,
Jared

I have them with both 5/8" and 3/4" threads, but right hand only. When I build bars, I use one fixed end, and one adjustable end. The dimensions on the 3/4" ends are, bushing width is 1.75" ( I can make them wider if needed ), And 1.625" in diameter( I can also use smaller bushing and get 1.375" diameter). ID is 1/2", but I can do them in 9/16" if needed. The threads are 3/4-16, and are 2.75" long.
I am always up to put together a package deal

Rod Ends

jhenry, I'm also building a triangular four link for my rambler, and like you I wanted 3/4 shanks on my rod ends. I found mine at http://autoweldchassis.com. They are stainless with poly bushings and at about half the cost of most other suppliers. I made my bars from 1" .156 wall D.O.M. tubing. The inside of the tubing is sized just right for a 3/4 x !6 thread. It would be best to thread both ends to simplify adjustments if you have access to a 3/4 left hand tap. Hope this helps, and good luck. Ed.

Threading both ends of the bars definatley makes it easier to adjust. But unless you are building a race car, they don't require adjusting. A street car only needs the four link adjusted once. Once the pinion angle is set, it doesn't change. That is why we don't do our bars adjustable on both ends.

I get an error message when I click this link. Does it work for others?

No.... The link dose not work for me either. But just do a google search for autoweldchassis and you will find their link. They have a good selection of stuff but I found their website a pain to navigate. I'm buying my parts from IAS here
