Do I really need Torklift Stable Loads

I replaced my overload springs with ones from an F-450 cab and chassis. They not only have more arch so they make contact sooner, but they also have a higher spring rate than the stock F-250 ones, so they make a bigger difference when they do engage. They cost me less than $40 apiece, brand new, and took about two hours to install. Between that and my Big Wig sway bar, excessive squat and roll are just a memory.
