ok heres teh deal...my goal is to run 33"X12.5 BFG MT's by installing a 2" body and 1" shakle lift...my questions are, is this enough lift to clear the 33"s, will I have to get longer break lines, and will I haev to regear to get the new meats rolling on the street? Any advice will be greatly appreaciated.

what type of Jeep?

I put 33x12.5's on my 85 CJ7, with everything else stock, and it was fine on the street. You'll probably need longer brake lines, but I would just go offroad, flex it out and see how it looks.

I still have stock gears in it now, and I'd really like to regear, but don't have the $$$ now. My Jeep is OK for offroad, but any minivan can take me at the light.

I think they will rub. I have 31's and just shackles and if I someone fat in the jeep and go over a bump the back will rub. Here is a chart from YJ.net Tire Size Chart[addsig]

Rubbing:
The rubbing will be largely determined by the back spacing of the wheels, and the amount of articulation you get. The amount of articulation with or without disconnecting the track and swaybars. If you are just street or even dirt road traveling you might be ok. Offroad in the rocks is a different story. Hitting the edge of the flares can be solved by the "TJ Flare" installation.

Brake Lines:
I have 5 Inches of lift with 33x12.5 Goodyear MTR's and I still run the stock brake lines (No problems on the ramp under full flex). If necessary, you can move and bend the stock brake line hold down bracket to give you more length (Closer direction)

Gears:
I ran the stock 3.07 gears that came with my automatic for years. Offroad in the rocks it was fine, On the highway it had some power issues. (Great gas milage though) Learning to downshift took care of that. In otherwords, it's not the best situation, but it works.
I didn't want to spend the money regearing the Dana 30 and 35. I did though (Because it was free) install a Power-Trax in the rear and a Lok-Rite in the front which made a big difference offroad.
The new gearing comes with the Dana 44's.[addsig]

Note:
The best way to check your Jeep out before trail damage is done is to find a club in your area with a ramp, use it and see what you need, or find a big rock or wall and test away.
It's cheaper and less pain to fix it first. [addsig]

No, the tires will rub the fender flares and body of a YJ. You need a good 4" of lift before the tires will safely clear the fenders.

will I have to get longer break lines

No, the axles are onle moving 1" away from the frame with the 1" shackle lift, so longer brake lines are not needed.

and will I haev to regear to get the new meats rolling on the street

No. I ran 33" tires with the stock 4.2L and it's livable on the street. You will ride the clutch a little to get moving, so shorter clutch life is possible. If you offroad, you should consider regearing later on.

Good luck. IMO you should save up and do the lift the correct way, 4" lift springs for a street jeep, SOA conversion if it sees trail duty.

Many times, even a 4" lifted YJ needs a little extra tire clearance with 33" tires. Spring sag and/or weight in the jeep will get the body into the tires. A 1" BL or fender trimming will quickly remedy this :-D [addsig]
