Hi - anyone have any experience with Summo Springs? They claim to reduce sway and eliminate bottoming out.

Advertising claims can easily sound appealing, especially when your problem seems obvious.
I'd ask around at 4WD shops and get the correct springs for the actual weight at the axle.
Local experience and installation is invaluable!

They don’t fit my 2004 Concourse no room front and back will go to bistein shocks my only option I think

Can't be too comfortable if it can reduce sway and eliminate bottoming out by themselves (not connect to the other spring). I can accomplished the same thing by welding the rear axle to the frame directly with a rigid offset
