As anyone on here ever ran 33s and 3 inches of lift on an XJ?

Yes.

yes

Not rare to find that setup. Just needs some good trimming and bumpstops.

If your careful you can do 35s.

I did on my last xj.

A lot of people ran this set up. I believe it was NewKindOfClown who set this standard.

One of my favorite setups you can do

lots of trimming/bumpstopping. sorta LCOG setup no?

I've done quite a bit of measuring and it looks like they will clear with our trimming and I'm planning on new bump stops soon since my current ones are rotten

I wouldn't even say lots of trimming and bump stop. Yes both are required, but just an average amount. It's has LCOG ideas but isn't really extreme. Much better than 6.5" on 33s like people used to run all the time.

Like I said it looks like from measuring I won't have to do any trimming on my fenders front or back I might have to trim some plastic from the flares if it rubs but that's no big deal but since this is my DD I would like to not trim the fenders

They may fit sitting there but as soon as you hit a bump they will eat fenders.

I know someone with 3" on 33s with factory fenders and flares. It sucks. Rubs constantly, and looks bad too.

Are they still using factory wheels ?
