you can go more then 2" in the front. the axle sitting on the bump stops is still 3 or 4 inches from the oilpan. i swapped in tj coils then cut out one coil from the bottom. cutting the coil out only changes the ride height not the spring rate. the only time i hit the bumps in the front is when i hit a hugh pot hole or rr tracks. as far as the rear i cut the lenght of the leafs down to match the next one..
