Spring suggestions?

[cbbr]

My '90 3/4 ton Burb is sagging in the rear. I have a 4" ORD shackle flip and zero rates. The stock springs are basically flat. I'm thinking 2-3" lift springs will cure the problem. I will be towing a boat, small camping trailer, etc, so I need to stick withe 3/4 spring rates. (I have read all about towing with a shackle flip, so resist the urge please). Any suggestions or does anyone have anything that they want to donate/sell??

Ok, here's my idea. If you go with lift springs, you're getting lift above stock. If I understood correctly, what you really need is just fresh stock springs. Obviously it's not worth it to buy new stock springs. My advice then is to install a long add a leaf. Make sure to get the long one NOT the short one. An add a leaf is easy to install, much cheaper than a set of springs, and will more than likely make your truck ride better since the rear springs won't be bouncing off the overload springs. A few years ago when I first started building my truck, I ran some Skyjacker add a leaves and they performed suberbely.
