1985 Rocky- Stiff Ride


I have an 1985 rocky that has leave suspension in all tires.. its a hard and stiff ride. I due to either replae the leaves or Re-condition them. But I Wonder if there is a way to make the ride smoother.. some kind of kit to conver it to spring suspension.

SOme one told me to take aout a couple of leaves suspension and add a Spring suspension from a Lada Niva (Russian Jeep). Any Comments on this?
