I haven't seen look at a Suzuki suspension, so I don't know how it's set up.
I do know on the Jeeps you have to cut the spring perches off of the axle tubes, and weld in new ones. It definitely has a lot more to do than just swapping springs, since you need to make sure that the driveshaft angles are good as well as the lateral spacing of the spring pads. Not difficult if you have the proper measuring tools and can weld that type of structural stuff, but still a lot more than just bolting in new springs.
I've always liked the ride you get from all the velocity sensitve valved shocks out there. I had a set on my Bronco a while back, they sure did work as advertised.
