I am thinking of replacing my springs in my 2000 GM. I do not have air suspension. I am thinking ofreplacing the rear springs with "cargo coils". Has anyone tried these and is it worth a try? The rear on the car sags with nothing in the trunk. I installed new shocks last spring, but the ride still feels sloppy.

 

cargo coils definately will raise it and also give the car more sway and different ride. have cargos on a car here and it rides way different compared to the other cars.

 

I have them on and it just gives the car a higher stance. I think the ride is just fine. If you are looking for something that is like a airbag quality then these are not for you. But overall they are great for the price and a quick fix
