I would like to replace the rear coils in my suburban with 1-2" taller coil springs for lift and heavier duty for towing. I'm getting ready to put some 2.5-3" coils in the front of my Dodge 3500. I'm wondering if the coils out of my Dodge will work in the Suburban. Does anyone know? I haven't measured anything yet so I have not a clue yet but I figure the progressive rate front coils off a diesel powered Dodge would be enough beef to handle the rear of a Suburban with a trailer?
