Message: [QUOTE="footlong70, post: 751709, member: 8456"] Take out all the leaf springs but the main leaf, just to center the axle, get a quality set of traction bars to hold the axle in place preventing axle wrap and use the ride rites to support all of rear weight (unless you plan on having more than 5000lb on the rear axle). Exact same idea as the R 4tech kit but much cheaper. Personally I don't trust the over spring ride rites with the upper brackets(seen a few bent and the grade 5 bolts shearing off). I have the inside frame mounted ones which IMO are beefier and setup to hold weight more directly on the frame. I ran mine for a couple thousand miles to see how it pans out and if it was worth while. After being astounded by the difference I took it a step further and beefed up the brackets from the ride rite kit for peace of mind and ditched the cheap u bolt setup that holds the bottom bracket in place(welded it solid), replaced the bags with long travel triple bellow bags(600PSI rated) with the same diameter. Increasing the volume of the bag softened the ride further more by decreasing the rate they pressurize in the same given travel. For on board air I added a AirLift wireless compressor kit for simplicity, convenience, price until I'm ready to put on a serious compressor setup on. Now I'm only using enough suspension to hold the truck up rather than the max GVW all the time. 55 PSI brings the truck back up to leaf spring height, 85 PSI supports a fully loaded box with a fully loaded rv hooked up to normal height. I have the ability to change pressures going down the highway to feel real time suspension changes and I have the ability to make the rear "kneel" to close to stock height for box use or fast trailer hook up (all firestone ride rite bags and my newer bags are made with internal bump stops so damage to the bag is no issue. Truck rides so much better than stock and its 7-8 inches lifted and running on 38.5" tires. She never has a saggy looking rear regardless of load. If I had to be honest, it rides like a well broke in f-150 and very "floaty" on the highway, with or without a trailer. My main concern was sway though. I expected an unstable setup with the bags being softer than the springs and being mounted 6 inches closure to the center of the truck then the leaves. However some how it feels just as stable as stock even given the height empty or pulling the rv. All and all I'm super impressed. Roughly just over 10k on the setup. For anybody curious I'm running 7" lift Icon dual rate springs in the front with a mish mash of random drop brackets, Newton traction bars with 8" traction blocks and a homemade shackle flip (doesn't do anything now that the springs don't support anything). And complimenting the setup is a set of ICON aluminum 2.0 nitrogen shocks all around which took the ride comfort to a whole new level. I use to be embarrassed about the way the truck rode, now I receive compliments every time someone new rides in her. [/QUOTE]
