    I'm going to make up some ball joint spacers for when I lift my 78, and I was wondering if they could be made out of polyurethene? I use this stuff all the time and have tons of it lying around, was hoping it would be strong enough, or do I have to use something stronger, such as aluminium, or steel?

    thanks
    Steve

    I made mine out of steel and steel is all I have seen. I would consider aluminum but definitely not poly.

    Steel is no prob. would I have to use a solid piece, then machine it out, or would it be possible to use some thick walled sqaure or rctangular tubing? How are yours constructed?

    They look simple enough to make, but don't they need to be thicker? With a 2" lift, shouldn't the spacer be 2"? Or is this another geometry thing?

    thanks

    another geometry thing.. i didnt believe it first. heres and example. take a 2ft long piece of metal, attach it to say the floor with a hinge. put a 3/4" piece of metal say 8" from the hinge, the end of that piece of metal would be more than 3/4" from the floor. i have been out of college too long, but it is simple geometry really.

    Yeah, I'm sure it's not a 1:1 ratio. Mine were 1/2" thick. I'm not sure how thick the "store" bought ones are...I just kinda eyeballed it had had a couple made up. I don't make any claims to be an expert on the subject, just relating what I have done. For some real answers you might try emailing someone like Fabtech for "proper" dimensions. I personally would go over 3/4".

    My fingers just can't keep up with my smooth runnin' brain!!
    I would not (personally or otherwise) go over 3/4" thickness on the balljoint spacer.
    Thanks Jon!!

    I'm just gonna lift it first, then if it needs a ball joint spacer i'll go from there.

    Thanks guys
