Rear spring rates

[Snowracer1000]

Sorry if I'm reposting an old topic but I have done quite a bit of searching and can not find any info. I'm looking for the spring rates for my 2017 suburban. I have the HD towing package z82 but am looking for a stiffer rear spring. I have the 23154238 and was looking at the 23154239's. They indicate increased capacity but no rates can be found. Anyone?

the Z71 package may offer stiffer rear springs but I think you'll need to go aftermarket (at least talk to them). It's been decades since I thought about spring rates and can't seem to find anything for these trucks after fifteen minutes. Seems also that Monroe got out of the spring business too.

I looked aftermarket but I can not find anything for the 2015+. I am really surprised this date is not provided by GM, when I work on fords the spring rates are provided by Ford. Don't feel bad I have looked for hours trying to find anything.

Now, it's bothering me! My go to used to be Monroe.

Well, I got close with Moog and Federal Mogul but no specs for the springs on my truck!

Also tried another former go to, Dayton Parts but I used to use them for leaf springs among other parts.
