2.5 lift on a 97 tj

[luis]

I want to install a 2.5 lift on my jeep. The front has the cam bolts from factory. But does the rear need pinion adjustments as well. I want to get everything figured out so I have all the pieces and the install can be alot smoother I was planning on getting the rough country lift its a basic one so it doesn't come with adjustable control arms

 

[TerryMason]

I've got a 2.5" on mine.

Things to think about:
1. Cam Bolts
2. Front track bar (either an adjustable one, or redrill the stock)
3. Rear track bar or bracket
4. Extended brake lines (optional, but my stock ones were fully extended when wheeling without a lift).

I didn't need to do anything with the rear angle, and didn't get any vibrations. However, the lift pointed out all the worn components in my system - I had death wobble until I replaced my ball joints.



Don't forget that we get a 10% Rough Country discount:

Yes I want to get rough country lift cause I hear good things and the discount aswell. I was just wondering bout the rear angle cause I see on a number of post mentioning rear angle. My jeep already have the front cam.bolts

I believe that the general rule is that you have to do something with the angles when you hit 4 inches of lift. You most likely won't have any problems with the 2.5" kit.

Did you also have to install the transfer case drop?

No, I didn't.

I'd try it without the drop and see if you get any vibrations. If you do, then you could do a transfer case drop, or you could look into something like a motor mount lift / SYE.

Well that's good to hear. I hope it goes smooth. I already had the death wobble once. Didn't like it one bit

Motor mounts easy to install. Any pros or cons of the motor mount lift and the transmission drop?

 

[TerryMason]

The pro for a transmission drop is that it's cheap and easy.
The con is that you've lifted your Jeep so that it'll do better offroad, then you lower the bottom of your Jeep so that it scrapes across rocks.

As for motor mount lifts, you should do a bit of research before doing that. The overall idea is that you raise the front of the engine which straightens out the drive lines a bit. It may help with minor driveline vibrations. Motor mount lifts are normally used as part of a high clearance skid plate setup.

Both of these options are affordable ways to help with driveline vibrations. The right way (assuming you've got the cash) is to get a slip yoke eliminator. There are a few threads that may help

Honestly, you shouldn't have to do any of this. Just pop the lift on and see if you have any vibrations. If so, install the lowering kit (which is most likely included in your kit), then take your time and decide if you want to change anything.

Yes I will try installing the lift and hoping for the best. Atleast I will know what to do. But if I do decided on lifting the engine then ill have to lift the radiator to or atleast the fan shroud?

 

[Bounty__Hunter]

It's not practical to lift the radiator, you either have to move the fan shroud upward, trim the bottom of the shroud to clear the fan, or install a 1" body lift. Check out Brown Dog motor mounts if you decide to raise the engine 1".

 

[TerryMason]

I installed my Brown Dog motor mount lifts as part of a 1 inch body lift. The body lift moves the engine bay up an inch, and the motor mounts bring the engine back inline with the radiator.

Lifting the motor is cheap ($100 or so), but not as cheap as the drop (usually included in your kit). The motor mount lift is also more difficult than the drop (but not overly difficult).

Well if I use any of the drop or the engine lift it will be worst case scenerio if the lift gives me the vibes. But its only 2.5 inches I shouldnt get any

I was wondering if my jeep would look good with 31x10.5r15 tires and a 2.5 inch lift kit will there be to much lift and not enough tire? I can't find any pictures on Google or anything like that

 

[Bounty__Hunter]

2.5" and 31" will work and look very good.

Thanks for the motivation. How much clearence between fender and top of tire can I expect?

 

[MattMayTJ]

I'm running 31's right now with a stock suspension and I have about 4 inchs of Clarence in back and about 3 inches in the front so your gonna have about 6.5 in back and 5.5 in front

 

[luis]

I just did some measurements and up front from the center of my hub to the bottom of the black plastic trim is 19.5 and the rear is 20.5. Is that stock or does it already have a lift? I never asked the previous owner bout any lifts
