Quarter eliptical? sagging? where am I..
Spring under springs are used to add lift, as they are arched more than spring over leaves. The earlier dakota leaves are used because they are spring under, after 97 the dakotas went to spring over, but the Durangos are spring under. I believe they have the 2.5" wide springs, so yes they would work. The will be long, but can be cut down. I would guess they are going to be alot stiffer than dakota or S-10 leaves as they are off a 4500lb vehicle...
