I What is wrong with leaf springs? The Ram does use coils yes, but it still doesn't perform like the leaf springs on the F-150. The coils might give a more comfy ride, yes, but towing went down 500lbs for one, while the F-150 actually went up recently to 11,000lbs. Plus in tests, the leafs still do better. I am sure that a proper coil could do just as good, if not better, though the sad thing is, the Ram with the coils kind of went a step backwards compared to what they used to offer. In the comfort deparment though, they went a step forward. Though there is nothing wrong with leaf springs. Hell, the Corvette still uses leaf springs and whips some a$$ with them as well.
