Replying to: karlw90 (Apr 05, 2007 7:27 am) - You may have your axles shift to one side more - You may have to change your pitman arm, which alters the steering geometry and can lead to more uncontrollable steering (death wobble) - If you go too big on the suspension lift, the control arms will be too short. The stock control arms are good to about 3" or 4", but any larger, and you REALLY need to go long arm or run the risk of an unstable/uncomfortable Jeep. - Cost - Center of gravity A 2.5" lift or so will cost a bit less (normally) and minimally impact axle centering and steering geometries. Also, if you think of the control arms as the radius of a circle, with a smaller lift, the axles and wheels rotate down and 'in' towards each other. A higher lift will bring them in a bit more, leading to a possibly harsher ride. A SWB TJ is bumpy enough.  Larger lifts will impact them more. While a 2.5" lift will fit 32's no problem, 33's will really fit nicely with that 1" Body lift, and 33's are about the ideal size for a daily driven Unlimited, IMO. That body lift also keep the frame lower, giving a better center of gravity (lower). That will help stability in turns. A body lift also opens the door for other mods, such as a tummy tuck to raise the transmission. As for the cost of the lift, I did the work all myself, but I bought the DPGOffroad Basic kit, and have since pieced together the body lift, motor lift, adjustable trackbars front and rear (to recenter the axles), and the quick disconnects for the sway bar for offroad articulation. That would be the ultimate kit on Dirk's www.dpgoffroad.com site. If you guys end up using him, just let him know Paul in Alabama referred ya. I don't get any discounts from him, but I like to let him know I'm keeping my word of letting people know about his EXCELLENT service and products. My entire suspension and lift is from him, as are all my headlights and driving lights (IPF). Even with my TJ being a 4cylinder, I have NO problems at highway speeds (up to about 78 or so). 33" BFG AT's would be great for Chicago, but I'm not sure how well they handle winter snow/ice. I hear the Mud Terrains actually handle it better and I know a LOT of people who use the BFG MT's on their TJ. While they may be a bit noisier, I kinda like the road noise my Jeep makes. I have TrXuS Mud Terrains, but ran the 30" variety of the BFG AT's prior to that. And before you ask, the quick disconnects allow better articulation offroad and give better flex, like this:  -Paul

Replying to: erickpl (Apr 06, 2007 4:28 am) 1) Will my stock 3.73 gears(4.0L/auto)be good enough for the much heavier 33" tires? Currerntly I have the stock 30" tires and I feel the power is very good. 2) the stock wheel lug toque is at 90lb(I think). Do we stick with the same torque spec when switching to a larger and heavier tire??

Replying to: 4rider (Apr 06, 2007 12:43 pm) Lug nut torque will remain the same. It's related to size, construction, and loading of the wheel rims and the location hardware.

Replying to: erickpl (Apr 06, 2007 4:28 am) One other question - probably a silly one - but.. did you get 4 33" tires and keep the stock on the back, or did you get 5? Also, if I kept the stock as my spare, and a 33 went flat, what - if any - harm would it do to my Jeep to drive on 3 33" and one 30 to the nearest tire shop?? (besides looking extremely dumb). Thanks again!

Replying to: 4rider (Apr 09, 2007 4:12 pm)  Differentials like to work for short periods at a time only. Regarding the bumper issue, you can get an adapter to move the spare up and out on the standard tire carrier. However, your solution is the best one long term. |

Replying to: 4rider (Apr 09, 2007 4:12 pm) I got a Teraflex spare tire relocator from Bob Supplee in OKC for about 25.00 or so and it moved the tire up/out so it cleared the bumper. Problem is, it wasn't up against the gate, so I ran the risk of weakening the gate itself. It was a stopgap fix until I got the carrier, which works SOOO much better. I got a deal from the vendor where he credited me basically the plain bumper price and I returned it to him. He sent me one with the hinge pin for the carrier and a full carrier for just the difference between the two bumpers. -Paul
