You can't use them on the front. Too light of a spring rate... You could use them on the rear, but you have to have the bottom of the spring modified to fit the spring cup on the axle properly. Or... You could cut off the old axle spring cups and get some for the rear of a 93-98 Grand Cherokee through Rusty's Offroad (rustysoffroad.com) and weld them onto your axle... That way it would give you just about limitless rear spring choices for spring rate/height...
