or just the normal straight bar C/A's AMERICAN MUSCLE right now until 12th has bbk upper and lower for 229......

How necessary is a adjustable upper control arm? For a DD car are the LCA'S brackets worth getting?

 

C.H.E. they're better and cheaper then those Summit clunkers!

 

So what is really the difference I thought all aftermarkets had poly bushings.....

 

Yes but C.H.E. uses a poly bushing that it injection molded, all others use pour mold which results in a much weaker bushing. They also use a Delrin sleeve between the bushing and the steel sleeve for permanent lubrication and no need for grease fittings. Another benefit to fitting-less arm is that the bushing is more complete and solid, they do not require channels in them to allow the grease to flow through therefore increasing strength of the bushing. I've driven on a few brands and these by far are the best. I've ditched all others from my product list.
