Does anyone have any experience with the ACDelco 45H2165 regular duty or the 45H2164 heavy duty springs in terms of ride quality? Or can anyone recommend any aftermarket springs that are replaceable to the factory springs on a 2005 Suburban?

 

Welcome to the forum....
What is going to be the intended use of the vehicle I think would be the place to start, HD springs are going to be stiffer and ride quality could suffer if you don't keep them loaded....

 

Hello,

I do go off road, mostly deep woods and beach sand. I dont tow, but the third row is frequently used and I put heavy stuff in the trunk. Would I be better off with regular duty springs with those load air bags? I just dont want it to sag when i have people in the 3rd road and the trunk loaded.

 

Which springs did you go with and how did it work out for you?
