Yeah, yeah...... I know...... the subject has been done to death a million times.
My thought here is to TRY to cover as many questions, concerns, options, etc. in one location.

I will EVENTUALLY be lifting my Liberty.
Having seen all the options out there, & having read all the threads, PLUS the "personalization" of popular kits, well,
there are still things I think can stand some clarification.

So.... here goes.

It's apparent that the 2.5" Frankenlift (in some form or another) is by far the most popular lift out there.
Being relatively inexpensive, and easy to install, this is understandable.
However, there are quite a few personalized versions of this lift out there.
Adding "clevis lift", extra spacers, etc. I know this is done for extra height & leveling.
JBA arms are a given, at least as far as I'm concerned.

Question #1. What is the primary reason some people chose to go with 4" rear springs?

:::::::carry more weight, little more height although with two extra isolators you're the same height

I'm not a fan of stacking spacers when it comes to suspension. Actually, I'm not a fan of spacers at all.

Question #2. Other than cost, are there any other benefits to the JBA Adjust-a-strut other than built in adjustability?

::::::::::adjustability is the main thing also if you add a aftermarket bumper later then you just crank it back up, also smaller diameter so the UCA will not hit the spring

Question #3. Is there any significant gain in ride height & tire size gained by going to the 4", or 6" JBA kit over the 2.5"??

::::::::With a "REAL" 2.5 inch lift you have the option of 254-75-16s, with a 4 to 6 inch you can more easliy run a 32 inch tire

I know 32's are the upper limit for a 2.5" lift. Will the 4 or 6 inch allow for 33's.... or larger??

::::::::::::::You need more than 2.5 inches to run 32s period, some have tired to run 33s but hard on the front diff and plus the fact with 4.10s you'll be loosing power, not worth it for maybe a 1/2 inch of height, unless you like looking at it since it is a DD

<EDIT> Regearing to 4.10 (or higher) with the larger tires is also a given. There comes a point when physics takes over
to keep the drive train happy. My concern with this thread is primarily the advantages / disadvantages of the lift height, and the reasoning behind them. <EDIT>
Most of us use our Liberty as a daily driver, as well as a weekend off-road warrior..... but let's face it, the cool factor always plays a part.
I like look of a lifted Liberty, and I'm only gonna do it once, so I want to do it right, and as informed as possible.

Question #4. What about Lower arms??

Like I said earlier, as far as I'm concerned, JBA uppers are a given. I'd also like to have greaseable lower ball joints as well.
Is there anyone making replacement lowers?? Or can I just replace the ball joints in the stock arms with greaseable ball joints??

:::::::::::::::::::No one makes replecemnet lowers replace LBJs with Moog greaseable

<EDIT #2>
Question #5. What about the RockFather lift from RRO??? Anyone try it??

I know they don't have the best rep for customer service, but is anyone using it?

::::::::::Some have used it BUT they only use OME front springs and shocks, the rear shocks and springs are of their own design or who knows from where, not worth it as you can buy a full OME kit for less money and less hassle

Final Question. Are there any other sources out there for me to research??

::::::::::::For what springs? shocks? other suggestions? Where ever you go regarding lifts you're going to get the same basic info

This forum is without a doubt the most complete source of information I've found regarding Liberty specific information.
I'm told the folks at JBA are ready & willing to answer questions, etc., but really don't want to start "pestering" manufacturers
until I'm actually in BUY mode for the suspension.

I would appreciate any and all input regarding this topic.
If you have a 4 or 6" JBA kit, please PM me with specifics, info, anything at all.
Same for those of you with any version of the Frankenlift, or even your own "custom" lift.

If you're going to install an aftermarket bumper and / or winch right away there are some other options but only then due to the fact the ride would be way to hard for most without.

Thank you for your time

Since you are going for a 245-75-16 tire why are you even thinking about 4-6 inch lifts, normal OME lift will do ya great
Also 4 inch springs in the rear with a normal OME lift even with a clevis and top plate may sit the rear up too high,
remember OME 927s with 1/4 inch top plate from JBA, 1/8 inch clevis in front and one extra upper iso in the rear sits you level and at a good height.
Little confused as to where you want to be height wise or what you are trying to do. Or are you one of those "overthinkers"

so for the ultimate,.... using your term, not mine

Been away this weekend but
how are you going to use the KJ?

what tire size do you want to run?

are you willing to regear?

again asked above but after market bumpers etc?

OK..... here's where I'm at right now:

2.5 - 3 inch lift is the target.... as I don't have an unlimited budget, and cost is a concern.

Frankenlift II in the front. (Saw you can buy a kit for the front only on their site.)
with JBA upper control arms.

JBA 2.5" coils & Bilstein shocks in the rear.

No clevis or plates up front for now.
I will pick up a set of upper iso's for the rear, just in case it's sits low in the back.
I do need to find new bump stops front & rear, as I couldn't locate them on either site.

Cost wise, this comes in at about $100 less than a full Frankenlift, and about $500
less than going full JBA.

However, I'm still kicking around the full JBA 2.5 as I like the idea of the extra clearance for the UCA's,
and the adjustability when accessories are added.

UGH! Someone needs to make up my mind.....

:frankie: Do Her up with a 6" 33's make you look like a Boss, CV's will hate you but you'll get good at changing them.

This Ultimate thread also appears to make no mention of doing a SFA swap..... I feel like we've been left out in the cold
