I just bought a manual 2006 Rubicon Unlimited with 90k miles (No rust!). The Jeep already had a 2 inch coil spacer lift and 17” JK rims with a 1.5 inch spacer adapter. The front was still rubbing on hard turns ( has 285 17R 70 KO2’s) so I ordered new 2 inch spacer/adapters. The shop took off the back tires and told me 3 studs on each side only had about 2 or 3 turns of the lug nut....not safe. Wondering if prior owner might have shortened the lug bolts to make the spacer fit...I want to put new lugs all around, but want to ensure I buy the right size. Suggestions? What I have read makes me believe I should not be having issues with stock lug bolt lengths with my spacer, but want other opinions. Thank you.
