Rubicon Express, Old Man Emu, and BDS make the best lifts. Spend the money to go with a higher quality lift, because it will pay off in the long run.

Also, lift size doesn't really matter in terms of engine size. The gearing in your differentials is what will make the difference. What rans are you running?

Unless you have the window sticker or are the original owner yours have been changed.

Im still waiting on some proof of a 4.0 with something other than 3.07 from the factory

Manual trans:

4.2L 258 I-6 and 4.0L I-6's: From 1987-March 9,1989, the standard manual transmission is the light-duty Peugeot BA-10/5 5 speed. On March 10,1989 the assembly line was changed and through the end of the YJ production run, 6-cylinder models received the stronger Aisin-Warner AX-15, 5 speed.
2.5L I-4's: For all years, the only manual transmission is the Aisin-Warner AX-5, 5 speed.
Note: In 1994, the slave cylinder on manual transmissions was moved outside of the transmissions bellhousing to allow for easier replacement.
Automatic trans:

4.2L 258 I-6 and 4.0L I-6's: For all years, the Auto trans is the TF 999 3-speed transmission.
2.5L I-4's: For '94-'95 models, the only automatic transmission offered was the Chrysler TorqueFlite 904 3-speed transmission. Prior to 1994, 4-cylinder models were manual only.

Hi Mike, Picked up a 88yj a month ago. 2.5 tbi. It's a project car for my son and I. Had to drag it home and been going through it. New tie rod, drag link, brakes all around, LH ball joints( really fun), new plugs, pcv, rotor , cap, wires and have replaced many vacuum hoses. Still starts rough but settles down when it warms up. Seems low on power and will miss occasionally. Do you have a source for a vacuum schematic as it still seems to run lean. Timing is ok. Any advice on the TBI or other diagnostics that you might recommend?
New to the forum and already I've found great info. I might have to take it in to the shop but( I'm cheap!!) and was hoping to get it figured out.
Thanks,
rob

1989 yj roll bar question

I have my jeep in the shop right now. They are installing a new rear seat but are telling me I need to replace my bars as they are to slanted for shoulder harness. Is there any other way to have shoulder belts in the back without changing the look of the jeep. As they want to install square bars. Any help is appreciated !!!!

You have the old CJ style roll bar. They are talking about installing a "family style" one from 92' and later.

Unless you have people riding in back stick with the lap belts

The electronic shift years could be wrong.

Some YJ's from 1987 came with the NP207, the rest came with the NP231

3.55:1 was available from the factory. I know it was standard on the Renegades... may have been optional on some other models. The stock tires on the Renegades were 30", so they had the deeper ratio.

I have a 89 yj with no motor or tranny. I bought a 4.0 that came out of 95. The wiring harness on the 95 had been all hacked up & torn off. What is the best solution to this problem?

Also the tranny I bought is a manual and there was an automatic on the 4.0 before. What all do I need to make the manual work? (I am new to this so any and all help is much appreciated!!)

I wouldn't recommend doing that swap, it can be done but you can swap in a V8 for the same or less price wise, another option is to sell the 2.5 and get one with a 4.0. The 4.0 swap isn't just a motor swap you have to change the tranny and transfer case as well, cut and weld new motor mount brackets, configure a wire harness etc. Just my .02 hope it helps and thanks for your service!
