The gears work the other way around, you will be in gear longer to get
up to shifting rpm.

For instance if I want to blow some carbon out on a straight track, I
can hit 20-25 mph in 1st, 52-53 mph at 4400 rpm in 2nd, 75 mph at about
3800 rpm in 3rd, 4th buries the speedometer and I have 'no' urge to find
out how fast 5th will go.

The trouble with giving absolutes on the lift you want is you want a
'borderline' setup. Some shake like hell, some don't at 3.5" of lift.

My CJ7 with it's 3" of spring lift is borderline and I eat u-joints
because of it. If I run empty, it rumbles, as long as I have a load on
to drop it that 1/4 or 1/2", no rumble. I have leaf springs and a
totally different Jeep than yours though. I also have a 1" equivalent
body lift the way my fiberglass tub mounts so have tons of clearance for
33's.

Your TJ is going to be at the cusp also which is why I personally think
the 1" body lift is the way to get tire clearance, not trying to push
the suspension envelope.

I personally would stay with a 2.5"-3" on the suspension (well, that's
what I did), then I would be sure I didn't have to put out for the SYE
and new driveshaft unless I wanted to go 'really' big. Won't happen, I
like mine the way it is.

That's EXACTLY what I am leaning on.....just wanted your opinion
though too. I am ordering the Rubicon Express standard 3.5 inch
suspension lift. I spoke directly with their representatives, and
according to them, I do not need to change out the stock CV shaft and
SYE because I am also dropping the t-case one inch with that kit. If
I were to purchase their 4 inch suspension lift, they told me I would
definitely have to replace those. I am also going to take your advice
and put a 1 inch body lift on for better tire clearance. I do not
want to go any bigger than 33s. And definitely no wider than 12.5. I
am actually contemplating going with 10.5 or 11.5 inches.

THANKS for the info.

That's EXACTLY what I am leaning on.....just wanted your opinion
though too. I am ordering the Rubicon Express standard 3.5 inch
suspension lift. I spoke directly with their representatives, and
according to them, I do not need to change out the stock CV shaft and
SYE because I am also dropping the t-case one inch with that kit. If
I were to purchase their 4 inch suspension lift, they told me I would
definitely have to replace those. I am also going to take your advice
and put a 1 inch body lift on for better tire clearance. I do not
want to go any bigger than 33s. And definitely no wider than 12.5. I
am actually contemplating going with 10.5 or 11.5 inches.

THANKS for the info.

That's EXACTLY what I am leaning on.....just wanted your opinion
though too. I am ordering the Rubicon Express standard 3.5 inch
suspension lift. I spoke directly with their representatives, and
according to them, I do not need to change out the stock CV shaft and
SYE because I am also dropping the t-case one inch with that kit. If
I were to purchase their 4 inch suspension lift, they told me I would
definitely have to replace those. I am also going to take your advice
and put a 1 inch body lift on for better tire clearance. I do not
want to go any bigger than 33s. And definitely no wider than 12.5. I
am actually contemplating going with 10.5 or 11.5 inches.

Cool!

If you go with the body lift, you can leave the t-case skid plate up
high and just raise the engine mounts to get the driveshaft angles the
same. This keeps your clearance way up there.
