I am new to Jeeps and new to this website. I don’t post much but I am on this site constantly. I would like to thank everybody responsible for this site. I can’t believe the knowledge on this site. All I have to do is search on this site and I find whatever I need. I am ordering 4.56 gears for my Jeep this week it has the 3.07’s and 33 inch tires. It is the 6 speed manual transmission with 4.0 and 2006 model. I changed my spark plugs and used what was recommended here and it runs like a different Jeep. If everybody goes by the suggestions here I don’t think you can go wrong. Just want to thank everybody here.
