I have a '74 cj-5 and am fixin to put a lift on. I was definately going to put a 4 inch on till I saw my bro-in-law's. It sure looks high on a cj-5. .Can anyone out please give me the pros and cons of each. I'm still leaning towards the 4 inch (can't be outdone by an in-law) but can be persuaded if the 2.5 is safer and more stable, which would mean better off road (wouldn't mind pulling his back over on it's wheels).
