Time for tricked out rear suspension...

[ASTAR]

Ok guys, I decided that I can't deal with the harsh ride of my truck anymore. It has 3/4 ton springs + add-a-leafs = STIFF RIDE I have been driving around a Cadillac Escalade for a few weeks and man I tell ya...I get in my truck and it's like YUK! Soooo rough. I know its not a fair comparison but I also need another inch and a half of lift to run the new 38x15.50x20 tires I got. The 37's fit well now but the extra width will require more lift. I already have 2" blocks + the stock blocks so more block is a no-go for sure. I looked at lift springs but they are usually pretty stiff too and if I don't go 3/4 ton springs, I lose the payload. I do tow with this truck. So I tought about doing a load airbag assist or something with 1/2 ton lift springs but the lift springs are $$$$$ and the bags are another $$ or so. So thats about 700.00. Thats not even considering what my truck might do to 1/2 ton springs as far as spring wrap from TQ. I figured that was too much to spend considering for that I could 4 link and bag the rear and it would work and ride a lot better not to mention eliminate any chance of axle wrap.
Here is the plan. I am going to start with some LARGE Rubicon Express bushings and also Large Rubicon Express Super Flex Joints. Add some 1 1/2 .250 wall DOM and end up with some nice upper and lower control arms. Getting some link mounts from Poly Performance for the frame and axle. I'm going to use 1 1/2 DOM to build a new drop cage for some airbag and shock mounts. Mount a 5 gallon stainless steel tank and compressor under the bed and a controller in the engine compartment (don't want cab clutter).
It will have 4 control arms and a track bar. The bags will be 2600# Firestones, Bilstein shocks, and all DOM and Rubicon Express components. The suspension linkage will basically be a copy of the long arm set up that I did in the front. I think it will give me the best of all worlds and I plan to document it all here so others can possibly benefit from it. I should end up with the ride height I want, the ability to carry weight in the bed, tow as good as it does now, have no axle wrap, and most importantly, feel soft on the road unloaded. I will also add the stock rear sway bar as my truck doesn't have one on it.
Any input throughout this endeavor is welcome...
Let the games begin!
