53 rear spring urethane bushings

[johnod]

I saw in a thread here mention of urethane bushing for rear springs. Does anyone know a source,I did a search, and followed what leads i found , but no luck. I found some for other vehicles, but not a 53 coupe.
I have to replace mine no matter what, so if i can upgrade at the same time that's even better.

Thanks for any help.

Is this the stuff?

Just be aware the urethane bushings will ride harders, a bit noisier and usually squeak more.

Good luck. I have found the front ones on C/K bodies to be a real challenge.

The front end pieces i've found already, it's a modified and is running newer front susp. not original.

You have to machine your own out of UHMW plastic.

OOO,, I don't have the machinery for that I'm afraid, but maybe I can find someone who does, what does UHMW stand for?

Thanks for the info.

Ultra high molecular weight. Sort of a improved variation on the cheaper commodity type plastics, polyethelene or polypropolyne

Polypro. But it is softer and has better lubricity properties than standard Polypro. It is harder than Urethane but softer than Nylon or Delthane. It is easy to machine and runs about $4.00 a foot.

I was referring to the front end of the rear springs, not the front suspension. Sorry, I guess that I was not clear enough. The topic says "rear springs" so I assumed that part.

Any idea who carries it?

Can you explain the first line quote above, not sure I understand that?

Thanks

Perfect.
I could use some of their tube stock and have it turned to correct dimensions. I assume you could reuse the steel "tubes" from the old bushings and just press them into the urethane, and then into spring eyes.


Thanks

I saw in a thread here mention of urethane bushing for rear springs.

Noltec, in Australia. They claim to have solved the harshness problems:

"Urethane suspension was originally developed for motorsport applications as urethane characteristics did not permit suitable road use. Urethane was hard, stiff and created unwanted vehicle vibration for regular day to day driving but provided track cars with strength and vehicle stability. As the decades rolled over and urethane technology developed, the motorsport market became a small, insignificant sector of a rapidly growing alternate rubber replacement in passenger vehicles."

I am considering ordering a set front and rear.
