Thats a Mopar 2" lift, probably measures closer to 2.5". I wouldn't say regearing is "necessary" but I'm hoping or assuming it will make pulling a little more comfortable. That trailer is about 2700# as is, give or take. I spent more time than I wanted in 6th gear. Never had a problem holding speed. Still got 14-15 MPG. I would have liked to use 7th and 8th a little more though.nice- is that a 2.5 or 3.5 lift? I was wondering if re-gearing was necessary with the lifted Rubi on 37’s if planning to tow. I have a stock Rubi on 35’s, and am towing an 1,800 lb (Dry) camper.
