I went with the Skyjacker 1" front springs, new Rancho RSX shocks, and no changes to the rear springs. Truck is nearly level after the install, with the nose just a hair lower than the rear. Ride is awesome (compared to the stock springs)! I also fitted 33x12. 50s with minimal trimming of the factory black plastic fender "flare". I haul a slide in camper, so I didn't want to the nose to point to the sky when loaded down, so I opted out of the 2. 5" springs and chose the 1". I think the 1" and 2. 5" springs are the same price, so it really depends on what you haul or tow, and if you are going to alter the rear springs at the same time. Can't go wrong with the Skyjackers, though. Seem very well made to me.
