My jeep doesn't seem to have bilstein's on the front, only the rear, but I might need to look again.
and I dont think the small events is what is killing my back, I think it is more of larger rolling obstacles, let's say 8 inch rollers and ditches, feels very bouncy and like a yo-yo, especially the rear end, incidentally the rear end is where the bilesteins are...
Does the Jeep have shocks on the front?
