buy the way a buddy of mine had the trailing arm set up and went to the 4 link he gained one tenth but lost all of his ride and manners. so if you already got trailing arms i would say keep them. however if you got leafs by all means get the 4 link. most all racers will agree that the trailing arms are the best set up thats why nascar still uses them. drag cars may gain slightly with a link set up but if your running a street truck i would think you would kick your self hard if you ditched the trailing arms...
