Changing out the suspension on my 54 Chevy 1/2 ton and was wondering the pro's and con's of panhard bar vs Track bar. Some parallel 4 link kits us the track bar and others require a panhard bar. What's the difference between the two? My intended use for this truck is a daily with hauling and towing. 4 link with air bags in rear and or 2 link with air bags. Just not sure which way is the best to go. Also will be running bags with mustang II in the front. I have the front down with just the coil springs where the running board bracket is at 7 inches but would like to go lower. Dual leafs in back and the rear bracket is at 10. Need some expert advise or experience.
