Like everything else there are pros & cons. If you have the stock bar you can only use the slim (3/8" bolt I believe) Energy Suspension links and they tend to bend. I guess that's why the stock bars have swivel joints in them (front & back). I have the 1.1/8" Addco bar on the rear with their 5/8" bolted link & lower springs and, that seem to work ok. I've heard other people have had better success just cutting the stock links shorter & welding them back together. Then just replacing the stock bushings for urethane ones.
What I'd like to know is what is best for a lowered front. I still have the stock bar & links, and Addco won't answer my e-mail about supplying me shorter links for the front. I wonder what they supply, if anything, for the fatter front bars they sell ??
