I have a friend with a racing Super 7 who is looking for polyurethane suspension bushings. In particular, his car seems to chew up the A-frame rubber bushings that attach at the differential. He does

MSC Supply has urethane bar stock. It can be machined, but it is not pretty. They'll send you a catalog, and they take credit cards. Their phone number is 1 800 645 7270. If you want, I can look up t

Try Ted Schumacher at TS Imported to see if he pours urethane for this application, or Chris Witor (in the UK) to see if he's got something.

If you're going to machine something, I'd recommend black delrin rather than urethane... also available from places like McMaster-Carr and MSC. I typically take a stock rubber bushing, remove the cen

(Reuse the steel sleeve, that is. You want the bolt to clamp the steel in place, and the delrin to slide on the sleeve; I tend to lubricate on assembly with silicone grease, and often modify the whol

At one time, Delrin was in favor. Just like Keith is saying, you buy it in bar stock and machine it on a lathe. I did this on my Elan 15 years ago and they work great. The ride is obviously a little

I would not suggest delrin in this application. It is too rigid and would not allow the range of motion needed on the rear a frame. Keith

Delrin is a trade name for toughened nylon, made by the Dupont Co. Its primary benefit is the ability to somewhat self lubricate. It is somewhat harder (Rockwell) than crosslinked polyurethane but mu

Can Teflon [PTFE] be used in these sort of applications? I have about 35" left after having to buy 36" minimum length! Thx for any advice . . . Derek

Teflon is pretty good stuff. Not as hard as delrin, but harder/firmer than rubber. The thing to beware is that it has a relatively low melting point (I'm remembering about 250 degF) and emits toxic f

Do not put a rigid or semi-rigid bushing in the center/apex pivot of a 7's rear A-frame. Preferably not in any of the 7's rear suspension pivots, but certainly not at the apex where it attaches to th
