Default i want to beef up my 03 suburban suspension

Anyone on here know a way to make the rear suspension stronger on the rear of my suburban? I want less sagging with a load and maybe about an inch of lift if possible. I have new front torsion bars (as high as they will go) and also spacers on top and bottom of the rear springs. Problem is that after my first trip with a 3000 pound load the rubber spacers are back to about factory ride height. I wanted tp put 2500 springs on it if they fit. does anyone know if they will? Thanks, Dave

I'm not sure if they make Add-A-Leaf packs for suburbans but if they do that would def be your best bet. Do some research and see if you can find one.

You could look into some stiffer 3/4 ton springs from the junkyard.

you could try a lift kit.... SkyJacker, RockKrawler, Rubicon Express, Claytons, etc...
