What lift does my TJ have?

Just bought this for my 15 year old. It has 31x12.50's and I understand they wouldn't fit on a stock suspension. There are no spacers on the springs so maybe the coils were changed?

Those tires are 31x10.50s and they will fit on a stock rig. Take a look at the coils and see if there is a rubber spacer wedged between the top of the coils and the coil mount. Definitely no body lift on your rig.

Looks stock to me. 31" tires usually come in a 10.5 width. They are on aftermarket wheels with less backspacing than stock which pushes them out a little more.

Nice looking Jeep. Lucky kid.

Thanks. I've had 4 Jeeps myself and wanted his first car to be a Jeep. Best part is he's on his learners permit now and won't be driving alone till at least Nov. So it's mine to use till then

What will it take to get 33's under it? It looks like there is plenty of clearance with the 31's so maybe just spacers?

You're right 31x10.50. I know better, been doing this a long time. I've owned 3 CJ-7's and the last was a CJ-8. I sold the 8 17 years ago. Must've been a brain fart.

There are no spacers

You are going to get many opinions on how to do this.

Cheapest? 2" Budget boost (spring spacers), and longer shocks. Add a 1.25" body lift with a 1" motor mount lift. The BL will get you the room for 33's, and the mml should cure any minor driveline vibrations you get with the added lift.

Same question about my TJ. Looks like it may have a lift but I'm not sure. Same tire size I believe as OP.

No BL maybe a slight 2" at the most, but you have some saggy front springs with a rake like that.

So 1.25 BL for 33's
BB, MML and shocks to make it right for off road.
Correct?

If they are 31's then it looks like you have a 2-2.5" suspension lift

Yes, but you dont NEED new shocks, its always good to upgrade but their not needed with a 2"sus lift

That will get the tires on there, and you will be able to off road with that set up.
I ran that way for a few years.

Being a former Jeep owner yourself, you know the effect that larger tires has on gearing and brakes. "Right" would be addressing those issues.

Sounds about right. The PO appears to have done a number on the front suspension. I've already had to address the death wobble.

You can have death wobble on a stock jeep, the cause of death wobble can have many different factors

For a second I honestly thought maybe you had a lift installed in the back only with stock up front, and I do suppose that is highly possible haha

True there is a thread about it

So I've started looking into the body lift and have a question. Why is the motor lift recommended with a body lift? Is it to keep the fan in the radiator shroud? How does lifting the motor affect the transmission and transfer case mount?
The last body lift I did was on a CJ and I just lowered the radiator mount to keep the fan position the same. But that was a 3" lift, I don't see how 1.25 would affect that much.

Trust me it will effect it, A mml doesnt effect the tcase/transmission mounts but it does tilt the rear of the tcase down, eliminating some drive line vibes. It also makes it so you dont have to mod the shroud

I'll buy the MML as suggested, but I'm trying to understand. If there are no vibration issues now, why would lifting the body cause the driveline angles to change?

It wont but it not only will it make the BL easier but then you could go up to a 3" sus lift without any problems
