MG MGB Technical - Seek Stiff Lower Control Arm Busings

Hello All,

I'm looking for stiff compound urethane lower control arm bushings. Does anyone know of a source?

Thank You

Steven Loe

Generally the V8 metal/rubber bushings are used for this application as they have very little give and long life. Very little left for urethane to bring to the table.

Steven, I can't find any source for Nylatron bushings now, although I have them in my midget I got them almost 10 years ago. If you have access to a lathe you could make your own from MSD filled Nylon stock which you can order from McMaster-Carr. I've made similar bushings for my job from Delrin on our small shop lathe and it's not difficult, the material turns pretty well with common tools.

The Moss red bushing are plenty stiff, I've had them on my car for a couple of years and am very happy with them.

Hmm... my last post seems to have vanished.

I used to run delrin in my MGB street car. I'd like to run something that's not quite as stiff as delrin, but is a pretty hard urethane.

I put the black Moss urethane bushings in my MGA, They were soft and within a couple of months, they were non-concentric and starting to fail.

A while back, I came across a web site of a British company that made urethane bushings in different levels of hardness. Does anyone happen know the name of the company?

Thanks!

polybush.co.uk? The shipping will kill you ;-)

Steven. I think the company is Super Pro and there is a lot of information on them, including contact information, in the archives. Steve S has commented on them at length.

Like the Wiz, I run the Moss red bushings on one of my cars and, so far, like it. In Arizona, rubber bushings do not hold up well. Even the "upgraded", V-8, bushings only hold up to a few years of regular use before beginning to break down. The poly bushings are supposed to stand up better. I will know better in a few years.

That's it. Super pro. Thanks very much!

Oh and these guys seem to have Nylatron: http://www.hdrogers.com/mgshop12.html

I'm assuming that "A frame bushings" = control arm bushings.

Thanks again.

The best bushings I've ever run are Superflex. They used to offer different shore ratings, but have since settled on a fixed rating for each area of the car. The bushings are designed to work as a set, offering ride quality where possible and performance where needed. They are a dark bluish-purple in color and they aren't the cheapest. They are however very high quality, offering machined (rather than molded) polyurethane and stainless steel sleeves.

I also run superflex bushes. See www.superflex.co.uk for UK supply, not sure if he ships to the US or if there will be a US distributor as well.

He does ship to the US, or you can buy them from Mech Spec on eBay.

There used to be a distributor in Arizona but they closed shop a few years ago. Recently I found a new US supplier but I can't for the life of me remember who it is!

It may be even cheaper to order them from Australia if you can, since that's where they are manufactured.

Does anyone have practical experience with Autobush? www.autobush.com
