Trail Jeeps in Golden will do it for $1000, while I got quotes of around $1500 from everywhere else I checked. I am going to go to 5.13 in my '12 manual very soon, then go one more size up on tires, from 35 to 37. Really looking forward to 5.13 instead of 3.73! Also, I am in Broomfield and have a bunch of great guys I wheel with here, so if you'd ever like to join us...
