Rear Coil Springs Sagging

[tahoe04]

My Tahoe looks like a prerunner. I pulled the blown Nivomats and replaced them with Bilstiens. The springs part #199021 have been ordered, but now two months later I am told they will not be available till late April. Will the 2004 springs from the Z71 w/o third row seats be a good match? My goal is to get the stiffist lowest ride hight stock springs. My guess is the
Z71 spring w/third row would be a stiffer but taller spring? Does any one have experience with these springs?
Thanks

what springs do you have on there now?

 

[tahoe04]

hotchkiss 1" rear drop super soft without the nivomat. truck is 3" lower than stock

 

[blueflamed03]

wow...so the 1" coils dropped it 3" with the shock swap?

 

[tahoe04]

lowered and spongy not good. Looking to put in z71 springs w/o 3rd row seats.

I am having a similar situation. I pulled my Nivomat shocks off my 01 Tahoe. It dropped my rear end about 1.5 inches. Even though my ride is level, the rear end is really spongy. Has anyone ordered the bilstein replacement coil springs or the same ones you can get off summit?
