Thx, understand. I do need to know the basics of my vehicle... still want to know what others have used and their experience with them.
Yes, looks like Ridetech has a nice link to vehicle weights and A and B dimensions on their calculator.

Suburban is spelled 'Surburban' if you search. Says typical weight with a V8 and 700R4 is 4,500, front weight is 2,280. Used their A-arm data for dimension A and B (10.94" and 16.94"), some trial and error with the angle and spring stroke and spring length.
Guesstimate using the Ridetech coils [73-87 coilover kit includes this spring: 59080800, Coilspring, 8”, 800lb] which results in
~700 lb for a cruiser/daily driver.
If I use QA1's 10" coil, 1OHTXXX, SPRING, 1O" HIGH TRAVEL 2-1/2" ID, results are ~
550 lb
I'll have to get QA1's A/B dimensions to be apples to apples, I guess.
