Thanks. Am I forgetting something that I should be changing as well? How
stiff is the ride with heavy duty coils/shocks on a TJ? I personally don't
like spongy rides (feel like boats). Any experience? I see you are
running a RE 4.5", but you might have had OME in the past for all I
know....

TIA.

Re: Lift questions

I have never installed an OME, but what I've heard is that the ride is
excellent. I have never heard a complaint about OME's ride. I just
wanted a taller lift, or I might have gone that way. My ride is a touch
firmer than stock, but I would NOT call it stiff. I could drive it
across the USA, no problem. I've driven in it for 16 hours straight with
only gas/food stops.

Re: Lift questions

Firstly, my reply seems kinda smart-ass now as I look back. Sorry.

I like to use www.napa.com for my parts look ups. I find that they offer
parts from several makers, and the cross reference works out properly more
often than not. Plug in the make and year of the model you want a part for,
then you can search the database for the parts.

I forget which, but it is a common size for which there is normally a bulk
roll of suitable hose in the corner of the store. I forget that you are not
in the States, but my local parts stores have rolls of various sizes of
hoses on a rack over in the corner of the store. The hose you need isn't
really important, that is it doesn't have to be anything specific - it just
has to be there. Having said that, I am not sure that you need to replace it
because it is long enough already to accomodate the droop, and the droop
isn't going to change very much as a result of your lift. This is easily an
issue you can address once the lift is finished.

The front drive shaft is long enought that it is seldom a problem with a 2"
lift. The rear is what is driving the bus in this issue. When you install
the tcase drop kit, you will end up with an angle for the tcase that is
pretty much a given. Set the rear pinion so the pinion shaft centerline is
parallel to the output shaft centerline. You can get the angle of the
centerline by using an angle guage along the bottom of the engine block, and
there is a flat surface on the diff that will be the plane of the pinion
shaft.

Somebody needs to jump in here and help me out.

I think that if you raise the motor an inch, you won't need the tcase drop
kit. Here's the deal on that.

With the lift, you are raising the motor and trans relative to the axles.
The body lift has no effect on the vibes, but it does affect other stuff -
but one thing at a time. So, you have lifted the engine AND the trans., and
you have disturbed the pinion angle - which your new goal is to bring back
into alignment.

First, I don't think the 2" lift will disturb the pinion alignment, so your
worries of vibes are unfounded.

I think your motor mount lift is a good idea. But, the engine/trans is
supported in three locations, one on each side of the motor, and one under
the trans. If you LOWER the trans and keep the engine in place, you get an
angle. Conversely, if you RAISE the engine and keep the trans in the same
place, you also get an angle. For practicle purposes, the angle you get is
going to be the same. So, you don't need to raise the motor and drop the
trans as a result of the lift, you need to EITHER raise the motor or drop
the trans. Get it? With a 4" lift, you need to do one or the other of these,
but with the 2" lift, I am not sure you will need to do either.

IF THE SPRING KIT COMES WITH A DROP KIT for the trans, then you need to
either drop the trans or raise the motor. If the springs do not have a drop
kit included, I don't think you need to worry about it.

PS
The belly up skid plate seems to me to be counter to the tcase drop kit. The
tcase is held by the skid plate, and the drop kit is essentially a package
of bushings that go between the skid plate and the frame. The skid plate
drops in the center where the tcase fits it, but the belly up skid plate
hasn't got the drop in the center, so the tcase will end up in the stock
location relative to the rest of the drive train if you lower the skid
plate, then raise the tcase with a belly-up skid plate. In this instance,
you may need the drop kit and the raised motor mounts. Think of the plane
that all of this stuff occupies. You need the combination of motor mount,
drop kit, and belly up that keeps the plan parallel. It gets complicated if
work at it hard enough, but if you just keep track of the plane it should be
pretty simple.
