Rubbing

I just put a 2" BB on my 93 zj and put 31s on. I didn't trim anything. When I turn I rub on my front bumper. I thought I didn't have to trim. How do I fix this?

I only rub on the bottom corner, just a little. How would I go about removing that section?

Use a pair of snippers or a box cutter. Goes right through the rubberized plastic. Unless you have the hard plastic? If so I would use a dremel.

I trimmed my front and rear bumper cover up to the first "line" where it concaves. Looks good and gives you extra clearance.

Most 2" boosts are actually 1.75"

Did you also replaced the isolators?

I extended my front bumpstops. That's it. I'll try a box cutter I guess. I want to trim the same amount you did, but I dot want it to look bad.

I put a 2.25 BB in mine with 31's kept the isolators. Had to cut about 1.5" to nothing wedge from the inner bottom corner to clear the bumper, no more rub. 2 washers in the steering stops keeps the control arms free from rubbing too, with stock larado rims that is.

I just trimmed an inch and a half of the bumper. It seemed to be my only option. It doesn't look bad. I have to take pictures in the day light

I had to trim the corners off of the inner part of the front bumper with a dremmel. Took 5 minutes.

I didn't have to cut that much at all. Just this little corner.

im suprised with a 2 inch boost you have to trim with 31's. I had to trim on stock height with my 30.5 inch tires.. i wouldnt think youd have to do it with 2 extra inchs.. maybe your springs are really saggy

I am not. I am at 3.5" and I still rub on my stock LCAs when at full lock reverse. that is a 245/75R16 witch is a 31x10.50 16 basically. That is on stock rims though, so it tends to make a difference with different backspacing.

Wheels with 3.75 to 4 inches of backspacing won't have tire rub.

sawzall with a fine toothed blade works well fro cutting plastic bumpers, or one of the mini ones with a 6 inch blade they run 30 bucks from sears or whatever but they do have many uses
