Hello , I put a leveling kit on my truck a few years ago and have since kinda wished I didnt do to the fact it made the ride more rough. I found out that the stock shock travel isnt much with it lifted 2.5 or so inches. I bought 4 new Rancho 5k's for a 4" lift so maybe I'd get a softer ride. My question is , Do I have to doing any more modificatons or change anything to get them to fit or will they just bolt right on ?? Thanks!
