What is the difference between auto ride and non auto ride rear? Is it length, spring rate?

Thanks

I don't think AutoRide has anything to do with the spring rates. However, with the Automatic Level Control, I believe the spring rate is slightly lower (softer) than those for non-ALC-equipped models.

I meant to tag you in that first one. By chance, do you happen to have the spring rate info between the factory springs?

No, I've never been able to nail that down. Spent many, many hours looking to no avail. Even the aftermarket ones are hard to locate but I have seen some before, just forget who!

Hey, if YOU don't have the info, then it may not exist outside of a GM engineer's top secret files! Next best is to measure the coils and estimate it from there. That's what I did when I was researching coils from other vehicles for my "drop coils".
