4.88 Gears Jeep Jk. I am running 2.5 teraflex lift with 315/70r17's (so basically 35's). A forum community dedicated to jeep wrangler owners and enthusiasts.
So your xj will act on 35s as if it had stock size tires and 3.73:1 gearing.
Jk owners have completely different engines but they seem to be afraid of rpm as well. I occasionally tow a light 4x8 trailer for dirtbikes or camping gear. Misinformation like this is probably why the guy in the jk at the daycare last week asked me if my jeep screamed on the highway after i told him it has 4:88's, he seemed. So your xj will act on 35s as if it had stock size tires and 3.73:1 gearing.
