I have a 3'' in my jeep now and have 33s on my ranger witch i want on my jeep,i need to know if some one has any insight on bumpstop lenths and wheel offsets,

You want to swap the wheels and the tires?

The wheels will bolt right up. Iirc, Ranger wheel backspacing is right at 5". Pretty close to stock XJ wheels. They'll fit but may rub the control arms with 33's. You can adjust the steering stops to prevent that.

Bumpstops. Just extend them until they prevent the wheels from rubbing. You may have to trim the flares a bit either way.

Well i know that i was wondering how long they need to be to keep them from rubbing the side of top of the body,ya know where u have electric **** mounted,and the ranger wheels are 4.5 '' backspacing,i know that the bumpstops is very crucial so u dont gut **** out of the front end

You'll just have to measure. I have 1.5" extended stops on the top and 1 hockey puck on the bottom on my 3.5" lift.

You'll just have to measure for the bumpstops, and maybe do a little trimming. I cut and folded my fenders, and added two hockey pucks in each coil spring for the bumpstops, and I'm running 33's on a 1.5" lift no problem. My tires are on 15x8 wheels with 3.75 backspacing.
