A soft ride with drop coils can be a bad thing if you drive on anything but smooth highways. As soon as you hit a bump in the road, a soft ride will cause the truck to smack the bumpstops and give you a nice jolt. Bang for buck, I think the belltech Street Performance kit with upgraded Hellwig rear swaybar is the best way to go. This setup runs about $685. You can always take it a few steps further and add the Spohn adjustable panhard bar, adjustable control arms, and a better adjustable shock like the QA1's, but then you are getting up into the $2000+ range when its all said and done.
