Yes, because the MOOG or equivelent use stronger bolts; but also use a metal sleeve, that the bolt goes through, between the two inner bushings instead of plastic ones. I say equivelent because I was curious and asked Kragen if I could look at the Enk Links for the ST from their supplier, and they were pretty much the same concept.
THE new ADDCO bar comes with NEW end links and all the hardwear...
JUST a word of caution, the brackets do not line up on the frame, you have to make the holes larger to give the bolts a straight shot or you could wind up cross threading the bolts or snapping them..
As Todd said, the Addco bar comes with all the hardware needed to install it.
The bar is so big, it is almost a little too big for the stock bracket mounting holes. We took a hammer and tapped the bracket a little smaller where the bolts would line up, but the bushing still fit.
