I know the desrip the in catalog says twice as stiff bushings, but nothing about metal itself. Is it thicker or is it all in the bushings? MM recommends the Ford HD uppers for most of the their stuff. But the steedas seem very nice for the price, they are way thicker metal and are boxed and got the ureathane as opposed to the rubber that the Fords have. But MM says the rubber is better for street and road coursing.

Any ideas?
