The ford racing uppers are $90 or so and the mm lowers are $321 a pair, i went with that combo because i checked on stangnet and the corral and it seems to be a popular combo that everyone agrees on.

Sounds like a good deal, I call them tomorrow and order the set along with some Tokico shocks/ struts.

You shouldn't? Do you even know? Going by your answer I'd def say no. You don't run poly at both ends unless you're strictly a straightline dude....any twisties and it'll bind up worse then the stock rubber bushing setup already does.

And MM all the way for LCA's if you feel the need to change them.

I've heard the 03/04 Cobra LCA's fit the 5.0L's. I was told it was a cheaper route to go. Anyone know if this is true.

I have to replace my ball joints, and wondering if I should just change the whole arm while I'm at it.

You know how the saying goes, if it breaks, make it faster. :)

I'm thinking of going the route of MM lowers. Do I have to change the upper at the same time aswell.

If I don't go the route of the new LCA, what are some ball joints some ppl suggest?

Thanks,
