Has anyone really verified that Rubi springs are 1" taller? I've got a
Rubi and I'm not quite sure it isn't a myth. However, I've never
physically compared to a standard TJ spring.
With 3" of suspension lift, you need to start looking at adj. control
arms, SYE/CV, track bar relocation, etc. Just buy the size springs you
want or stick to the spring spacers ONLY.

Mike and Bill --
You both have VERY good points and I am grateful for the information
that you've provided to me. I am just really new to this and don't
want to have to do this lift 5 times over to get the results that I
want.
So on that note.....TW
The instructions that you gave a couple of posts above (#1-#6).....I
assume that this is good for the 2.25" spacers as well.....not just
for 2" spacers? (I am assuming that 1/4 inch would not make much
difference, but with stuff like this, it wouldn't surprise me if it
did make a difference).
Mike....
If I just do the 2.25" spacer lift like you are suggesting, would a 1"
body lift in the future cause any headaches in the future as far as
the installation goes? I have heard some body lift kits are not
compatible with jeeps that have A/C.

Mike and Bill --
You both have VERY good points and I am grateful for the information
that you've provided to me. I am just really new to this and don't
want to have to do this lift 5 times over to get the results that I
want.
So on that note.....TW
The instructions that you gave a couple of posts above (#1-#6).....I
assume that this is good for the 2.25" spacers as well.....not just
for 2" spacers? (I am assuming that 1/4 inch would not make much
difference, but with stuff like this, it wouldn't surprise me if it
did make a difference).
Mike....
If I just do the 2.25" spacer lift like you are suggesting, would a 1"
body lift in the future cause any headaches in the future as far as
the installation goes? I have heard some body lift kits are not
compatible with jeeps that have A/C.

Mike and Bill --
You both have VERY good points and I am grateful for the information
that you've provided to me. I am just really new to this and don't
want to have to do this lift 5 times over to get the results that I
want.
So on that note.....TW
The instructions that you gave a couple of posts above (#1-#6).....I
assume that this is good for the 2.25" spacers as well.....not just
for 2" spacers? (I am assuming that 1/4 inch would not make much
difference, but with stuff like this, it wouldn't surprise me if it
did make a difference).
Mike....
If I just do the 2.25" spacer lift like you are suggesting, would a 1"
body lift in the future cause any headaches in the future as far as
the installation goes? I have heard some body lift kits are not
compatible with jeeps that have A/C.

Yes, the 2.25 as well. As far as a 1/4" making a difference...as a rule,
no. Vibes are a funny thing, though. Basically, it seems that what you
are trying to do is get to the threshold of vibes so you don't have to
spend the money on the SYE/CV kit but get the highest lift you can.
Problem is, the threshold is not a 'carved in stone' lift amount. You
can lift 10 TJs 2.25" and probably one or more of them will have vibes.
If you want to play on the razor's edge, you need to be prepared for the
worst case. Expect vibes on the 3" susp.lifts.

That's what I thought. I didn't think there was a difference in the
height either. In order to save myself all the headaches (and you
poor guys as well :D), I have decided to go with a 2.25" coil spacer
lift with the new shocks and my stock springs. I will most likely add
a 1" body lift for 32" tire clearance in the future. Which will still
give me roughly 5.5" of lift (with the 32s). And that's close enough
to what I wanted overall anyway (I wanted 6" of lift overall, but will
settle for 5.5").
Someone mentioned that when you get over 2" of suspension lift (Mike I
think this was you), that you start to have all sorts of headaches.
Not to sound silly, but will the 2.25" spacer vs. the 2" spacer make
much difference in the way of potential headaches associated with
driveshaft, adjustable control arms, etc.?
