Picked some up, can't find specs? Anyone heard or used these specific part numbers?

I had a list at one time that listed out the rear spring part numbers and their spring rates, but I didn't find it particularly useful because the Z71 springs are readily available, and much stiffer than the stiffest TB spring.

For $30 on the pair I'm sure they'll be night and day over the OEM Envoy springs.
Pairing with Bilstein HDs.

Yeah that part number is for the Tahoe,
I just got the shocks in and waiting on the rest of the parts.
Once it comes back I'll report back or put a build thread together.
The only thing I have to compare it too will be my 2013 Tacoma vs OEM and upgraded suspension on the Envoy

Has anyone ever heard back from the guy who put z71 springs on the rear and was moving his rear springs to the front? Do we know anything more on that?
