285's slight tire rub. How can I fix it?

My '01 LB7 has (according to the previous owner) a leveling kit. When I crank my wheels to the right, the outer side of the driver side wheel hits the plastic lip on the lower part of the bumper. I actually need to do something about this now as I got new fog lights (mine were missing) and I don't want to stress them out or have issues with them caused by a rub.

I had brand new 285/75/r16's put on it last year. Some people mention trimming it, and if that is the cheapest and easiest way to fix it I think I'll do it. What would the best way be to trim it? I am, of course, open to other options.

I trimmed a small wedge shaped piece off the corner of the inner lower bumper cover, problem solved. Mine only needed about 1/2" extra clearance.

Have you adjusted the torsion bars yet?

It could have keys. They may just need to be adjusted.

Do you have any pictures by chance? How did you do the trimming? I think 1/2" is all I need.

I'd rather not do this as it's apparently harder on the front end.

Where can I find out more about this? Would an alignment shop be able to do this?

Look and see what keys you have. Even stock you can adjust them without affecting the ride quality or being hard on componets. An inch is all you would need.

I don't know much about suspension. Where are they and what do they look like? How do I know what kind I have?

Just trim the lower valance and be done. It's not too hard. Then no more worries. The problem is, not everyone's experiances will be the same, because every tire is different, and every truck is different. I have owned several 2500 HD's and on one of them 285's rubbed, and on another they didn't rub at all! Figure that one out!

An alignment shop will be able to do it. It will need a alignment after you do this as well.

Not always. My T-bars are cranked all the way up. I had it checked and they said it wasn't off enough to even mess with it, and it wears tires perfectly. It wouldn't hurt to have it checked though, just dont let them screw you and align it if it doesn't need it.
