Post subject:  4" or 6"
I have the frankenlift with 3 rear isolators in the rear and i was wondering how the jba 4" and 6" lifts compares to that in terms of rear clearance. I would like to gain more clearance to run chains in the rear. Right now i only have about an inch of clearance at the closest point. Would the 4" be enough or would i have to go to the 6"? Thanks.

I think troy posted pictures of his skyjacker with their HD coils, which is basically a frankenlift.. next to tokyo joes JBA 4" and TJKJ2002s was actually taller

In the front. You need to review the rear.....just don't look too long. People might talk.

You don't gain anymore ground clearance with a FL, JBA 4 or JBA6 since the tires is what gives you gc and all three allow the maximum tire diameter 32". They do have an impact on MPG though. The bigger lifts will make your KJ "taller" though.

4 is a nice height

i beleive the clearance he is looking for is in the wheel wells, which does change with lift.

I am running the franky II with 2 extra rear isos and netted 4" after settling. What are you measurements center hub to bottom fender? Tire size?

Why do you have so many isos? I only have one in the rear. Does the FL settle that much that you need more than one?

It did for me. I was 1/2" lower in the rear after it all settled. The rear was 3.5" and the front was 4", so I added the extras and it is 4" f&b now.

Well, i'm not sure, maybe it is just me, but i think i got ripped off in the rear. When I first put 32" tires on they were practically rubbing back there standing still. I ended up with 3 isos and 3 hockey pucks and they will still rub when flexing. That is why i was considereing the 4". My front is still higher and i have 3 isos in the rear. Do you think the 6" in the rear would make the rear end up too high with just a franky in the front?

JBA's 6" lift uses long arms in the rear that require cutting the old LCA mounts off the unibody and welding new mounts on.Unless you do this you will always have that problem in the rear since any lift on a KJ moves the rear axle closer to the front of the rear wheel well.To re-center the rear axle you will need to use adjustable LCA's and have a modified upper tri-link made so you can get the pinion angle back into spec and not facing down which will occur if you just use adjustable LCA's to re-center the rear diff.

You got 3.5" of lift in the rear without isos? How is that possible? I thought the frankenlift was a 2.5" lift with 2.5" of lift in the front and 2.0 " of lift in the rear to even it out.

Now, i never measured my before and after in the rear so i do not know what i'm sitting at. i figure i got about 3" in the rear from the isos and springs. In the front i measure 3.25" over my pre-lowered springs after settling.

I got 3.5" of lift after I put the lift on in the rear. The Franky is billed as a 2.5" but I took before and after measurements and was at about 4" in the rear and around 4.5" in the front right after I lifted it at 33,000 miles. I put the extra isos and got 4" out of the rear and the front has been at 4" even with a steel front bumper.

What is the measurements from the center of the wheel to the bottom of the finder flairs on a Franky lifted kj?

Looking at jba's website he says his mounts can be bolted on. That modified upper tri-link issue, does that 6" tri-link extension jba has not help aleviate that issue.

I don't have my jeep here to measure and I can't remember. :?

With the thin sheet metal back there I'd have a very hard time trusting bolts alone.The tri-link extension has some adjustability but not a whole lot.

I’m very happy with the Frankenlift II. I might swap out the gasser HD coils for the CRD HD coils in the front because of the heavy bumper and winch makes her a little soft and squatty in the front. Overall, the ride quality is nice, the height is about perfect, and the addition of 4:10’s will be nicely suited for a 30.5- 31.0” tire. I’m as happy as a pig in the mud. Without going SFA, that’s about all she can do. That’s why I’m building a JK Wrangler. The Liberty can do a lot, but I wouldn't call her the ultimate trail rig.

I measure the front as about 20.75" from hub center to fender bottom and the rear is about 20.5" from hub center to fender bottom. I'm not sure what the front was before i put the bumper and winch on but my winch is a little lighter because of synthetic rope line.

There is a fair amount of clearance in the front because of the bumper and pounding the pinch weld with a bfh. TJKJ is right i think when he says more lift actually gives you less clearance to the front of the rear fender area because you control arms push down in an arc pulling the tire closer. So more lift may not necessary be the solution.
