I'm getting ready to take out my spacer lift and my bump stops are rotten to the point of falling apart. I'll be going back together at stock height, no lift. Looking for replacement bump stops, I see Energy Suspension lists some for the front but nothing for the rear. Looking under the Jeep, they appear to be the same front to rear. Is there a difference between front and rear bump stops? Any other sources where I can get stock replacements for a reasonable price?
