I have a 97 TJ with a 4 banger so i have 4.11 gearing. What i want to do is go with 4.88 to get my speed back with my 33's. I have a buddy with a set of 4.88 gears for the rear but not thr front. So my question is would it be ok to run 4.11's in the front and 4.88 in the back? Also in the front i have a detroit trutrac but not the rear. So my other question is would it be ok to run the detroit in the front without having a rear?
