FYI for anyone thinking about these, they are great! Recently had Wildside Jeep Customs in Naperville IL install these. I really like the change from Bils and Rancho 9000. But be cautious. The Trac Bar bolts need to be reversed. Otherwise they will dig right into the SS body. Its not cleary explained in instructions or video. Yep we found out the hard way. But the crew at Wildside replaced and reinstalled. Need any work go see Wildside!!
