2008 Suburban 1500 LS increase spring rate

[96Impala]

I have a 2008 Suburban 2wd LS that I wpuld like to increase the spring rate on. It currently is too soft.

Has anyone tried spring rubbers like in racecars in their vehicle for this purpose?

Has anyone tried to take 2500 springs and put them into a 1500? Or springs from a 4wd 1500 into a 2wd?

Want to do something to keep it from being so bouncy.
