OK I have a 2000 Jeep grand cherokee and i put the 2" budget spacer kit on there and im just not happy enough... my friend wants to sale me his 3" lifted coils for his grand cherokee because he is going to the 4"...here is the question. If i add the 3" springs to the 2" spacers do i need the track bar for the 5 inch lift and all the other components from the 5 in. lift besides shocks, or does that 2" mess with nething like that?
