If your looking for a smoother ride. Just change out the 3/4 ton coils and get some 1/2 ton coils. Same for the front. Changing from coil to leaf springs would be a major pain but you could reuse your rearend. Just have to weld on some spring perches. If you still haul an occasional heavy load. Add some factory helper springs. I've got a set for ya but I'd have to remove the factory brackets. Lot's a rusted bolts, lol but I'm willing if interested.
