Fitting 33\'s on a YJ

I've got a friend that wants to fit 33x12.50's on the YJ he just bought. I was thinking of a one inch body and engine lift and a 2 1/2 or 3" suspension lift with sway bar disco's and some fender trimming if needed. I also plan on having him get all the other things like gears and a SYE kit, etc..., but I just wanted to know if there would be room for the tires at full flex and lock? or will he need to get a 4" lift? Thanks!

3 1/2" total did the trick on my 94 YJ. Little fender trimming and steering stop adjustment was needed

If you use a STIFF 3 inch suspension and a 1 inch body lift you will be ok. If you use a SUPPLE suspension lift you will be in trouble.

My 90 YJ with 2 1/2 inch Old Man Emu lift needed 2 inches of body lift to clear 31s on some of the tougher trails. I still have the bent fenders and cut tires to prove it.

Re: Fitting 33\'s on a YJ

I have 4in currie springs on mine, and 1/2 shackle lift and I still rub in the back a lot when I flex. The currie springs really flex well though...

4in currie lift, 4.56's, true trac, and 33's.. yeah it's a start!

Re: Fitting 33\'s on a YJ

Well, here's my story, told over about 4-5 years of wheeling.

Put on 4" lift (pro comp)
Put on 33 x 12.5 BFG MTs (and 4.10 geared axles.)
Wheeled good. [img]/wwwthreads_images/icons/smile.gif[/img]
Springs started to sag, and I was hitting in back. Bumpstops in kit don't stop this from happening.
Put on some 1" longer shackles. [img]/wwwthreads_images/icons/smile.gif[/img]
Wheeled good.
Springs started to sag some more, and I was hitting in back again.
Put on a 1.25" body lift.
Wheeled good.
Rubbed the flares a tad.
Put on TJ flares. [img]/wwwthreads_images/icons/smile.gif[/img]
Didn't rub when I hit the bumpstops.
Took out very sagged 4" springs (my buddy's new 2.5" lift had as much arch as my 4" sagged springs) and put in some 3" lift Ranchos that are practically brand new I got at a swap meet from a guy who sold his jeep.

Now there's lots o' room, with the 3" springs, TJ flares, 1.25" body, and 1" longer shackles. [img]/wwwthreads_images/icons/smile.gif[/img] It's a good combo. But, it didn't rub when the 4" lift was new, either.

Do a spring over. I have a spring over with add a leaves made from stock spring packs, and a 2" body lift, and added 2" bump stops. 33" Swampers don't scrub, if flexes great and still rides good.

"Honestly, I didn't lift the Jeep.
I,um..ah..lowered the axles"

Re: Fitting 33\'s on a YJ

well i don't have 33's but my condition might help confuse the matter a little more! i have 32's that rubbed in the rear at the slightest dips/bumps with a RE 4.5" susp lift. they rubbed on the flares. i put on a 1" body lift and now they rub only slightly when on 4wd type situations. i have not really EXTREMED with my 32's YET but can't wait. i have 4wheeled maybe 200 miles with the current set-up but no rock crawling which i do closer to home but too hot here in the desert.
