Default How to determine lift on used jeep?

Recently purchased a 93 xj i6 4.0 5sp. How do i determine lift and suspension specs? It came with Teraflex stickers on the side I can tell there are new shocks and springs on the front end. not sure about the rear. will add rear in photos later. Thanks for your feedback!

front is lifted, but unsure about rear.


You can tell by looking there are a few inches added but I have no idea.

He said there is enough room in the wheel well for a tire that tall as long as you keep it narrow. You might need the slightly curved lower arms at most.
I have found in mud and snow that if the tire can cut down through it to more solid ground underneath it goes better. This is why Model T did so well considering...

That, and you're gonna significantly widen your turning radius. Out of curiosity, I put a 33x12.5 on my XJ with a 4" BS wheel and no lift. I couldn't turn my tires, and I couldn't drive over a stick without rubbing, but it fit.
That is why you have to keep the width down to 8" or 9" wide and stock backspacing. Taller works if narrow and tucked in with a little added to bumpstops to limit upward travel to just below the top of the inner fender. Width causes rubbing on the control arm and sway bar links more than diameter. It is becoming more difficult to find tall narrow tires as everyone wants the extra wide tires now days since they handle curves at high speeds better and give better traction on dry pavement.

I have also found this to be true, as long as there is solid ground under the mud or snow. We had 1950s Farmalls on the farm with the tall skinny tires that we always too when it was muddy and left the newer tractors with the fat tires in the shed so we didn't have to pull them out. On the farm we had about 5 inches of sandy soil sitting on top of hard clay and fat tires on that mud was just like driving on ice once you went through the mud and onto the clay. The skinny tires put more pressure on a small area giving them more grip.

I had 30x9.5s on my Comanche. I've done it myself, and I know they rub when you turn. Diameter and width are both factors in that equation, and the steering stops need to be adjusted if you don't want to chew up your tires on the LCAs

I have 30x9.5 tires on stock wheels on a stock height Comanche and they don't rub, but I didn't buy the tires new, and they may run small.All Lift & Tire questions go here!!!-photo526.jpg it never makes it off the pavement though, so I don't know how it would handle flexing

Looking for recommendations for my XJ. It's currently got 2" spacers in front, and unknown springs in back. I'm happy with the amount of lift in front currently, but I do plan on going another inch or two higher down the road.

My current rear springs are sagging really badly, and I'd like to replace them and get rid of my reverse rake. Quadratec has both the Crown and the Omix-Ada HD springs on sale.

My thinking is to get a set of HD springs(any preference between the crown and omixada?), and then down the road add a shackle relocation kit, lift shackles if necessary, and hopefully 3.3.5" lift springs up front to even it out when budget allows for upgraded steering/track bar components. Am I on the right track?

Things get very complicated over 3"......Lots of new parts needed in order to make it stable and safe......things that are not obvious....until you try to drive it. If its just an off road toy, then its easier to modify.....

Rubicon Express and Tuff Country use silver. Tereflex is typically black IIRC. The rear on that is definitely lifted at least a couple inches.

Hi there, first post. I'm needing help with spare tire placement on my '01 XJ.

I can't find a good solution to carry my spare. I have 31's on my Jeep and I know that they fit in the cargo area but I've built a cargo box in the back that I use for storage and it fold into a bed for camping so I don't want to keep it inside. This leaves me with either the roof rack mount or rear mounted. The only issue here is that I mountain bike multiple times a week and leave my bike rack locked on the hitch to speed things up.

I've heard that the roof rack is doable but a pain and has CG and MPG drawbacks and most people go with the rear mount, but is there a way to mount the tire and still have my bike rack on there without having to drop $1k for the whole set up or having it all stick out an absurd amount.

Hope this makes sense, thanks in advance for any help.

you will have to fab something like a hitxh mounted tire carrier with a place for your bike.

on a differrent note, lets see your cargo box/bed thing

Good morning Martlor... I have an important question you may be able to help me with. Are you handling Toyo Light Truck Tires? I just started looking but maybe you might have some possible recall information if you handle these?
