I wouldn't put poly in that location no how, no way.
And yes, I've been there and have the "lucky we weren't sued" t-shirt.
You shouldn't put poly in that location.......... EVER.

Use Moog steel-lined kit K8157.

Would you clarify this?

 

The struts require flexing of rubber.

poly bushings are to stiff. as the lca moves up and down the rubber bushings flex. poly bushings will not flex and the strut rod will bend up and down and break. Moog makes the best rubber strut rod bushings.

 

The supposed advantage of urethane is it does not compress as much as neoprene. Some places, like sway bar bushings, this is OK, since the worst than can happen is rattles or squeaks. But the strut bushings provide movement as the suspension rides up and down. Urethane forces the strut itself to bend to provide this movement.

If you want to kill yourself, fine. But your strut might break on the street, causing you to lose control, and kill my Mom. That's not OK.

Someday a lawyer is going to take on such a case, and a manufacturer of these things is going to get burned. Until then, we need to get smart.

Already happened. A legal technicality stopped the prosecution's efforts.
End result- We stopped selling poly strut rod bushings. (A piece of paper
identifying said product as off road/race only will not stop legal action,
in case anyone is wondering)

To those who were nice enough to explain, thank you.

A drive by "do this" or "don't do this" without at least a basic start of why is as worthless as the electrons it was sent on.

FWIW, polyurethane just like rubber has different hardness: durometer. You can easily get polyurethane as soft or softer than rubber. Here is an awesome picture showing the scale:

I'll wait for the Moog bushings, I'll compare to the poly bushings I have. The poly were fairly stiff.

 

Yes, you can easily get polyurethane as soft, or softer, than rubber. What you CAN'T get easily are polyurethane Mustang strut rod bushings anywhere NEAR as soft as rubber.

 

I have no clue on what is available or not for the Mustang strut rod bushing other than the one I have(Prothane??)

The point of my "you can get poly as soft as rubber" is it debunks the claim of all poly being stiffer than rubber.

I'll see how the Moog compares to the poly I have.
