Actual lift results favor

wolverine · **Posted:** Mon Oct 12, 2009 10:15 am

For those of us with no lift
currently but are planning one soon
I am hoping to get some
details from a few of you with lifts.

I remember seeing a nice post by mtnluvr ( I think )
in which he posted measurements of the
front and rear wheel wells after installing a jba 2.5" lift.

I believe the lift in the front ended up just over 2.5" but
the lift in the rear was far less

would any of you with lifts of various heights mind
measuring the distance from the center if your wheels
up to the body in front and back and posting the
results for me and the group?

Thanks in advance

You want from the middle of the rim to the bottom of the fender?

wolverine · **Posted:** Mon Oct 12, 2009 11:27 am

Yes, that would be great. I am just trying to remove any lift caused by different tires that people have.

I'll post '09 purely stock measurements tonight.

For anyone posting measurements please post them to the stickied Suspension Setups thread
http://www.lostjeeps.com/forum/phpBB3/viewtopic.php?t=45366
to keep all of the info in the same place.

I could post those measurements but it would be with 245/75/16 Tires not the stock 225s

wolverine · **Posted:** Mon Oct 12, 2009 1:38 pm

That is why I asked for center of the wheel up to the fender

unless I am just thinking about this all wrong that
measurement would not change if you have different size tires

please correct me if I am wrong

Elt31987 · **Posted:** Mon Oct 12, 2009 2:47 pm

Yes i would assume the smaller the tire the bigger the gap between the middle of the rim and fender would be but others will chime in to confirm

Boblemoche · **Posted:** Mon Oct 12, 2009 2:59 pm

tires dont affect the measure from top fender to middle rim

Elt31987 · **Posted:** Mon Oct 12, 2009 3:10 pm

Stock 09 KK

Center of wheel to fender:
Front Driver: 17 3/4"
Front Pass: 18"
Rear Driver: 18 3/4"
Rear Pass: 18 7/8"

thanks digger. If we are measuring the same way then that
would make your lift 3-3 1/4 up front and 4 3/4 in the rear.

The JBA 2.5 (from MtnLuvr)

In the below dimensional info, "Ps"=Passenger's Side and "Ds"=Driver's Side:
1. Front Wheelwell (FWW) settled about 1" (Ps from 34-3/4" to 33-3/4", Ds from 34-1/4" to 33-1/8")
2. Rear Wheelwell (RWW) (Ps from 34" to 33-3/4", Ds from 33-1/2" to 32-7/8")

My well

I don't know

Both sides are almost even

1. Front Wheelwell (FWW) 35.25 inches
2. Rear Wheelwell (RWW) 38.25 inches

So basically I'm looking at + 1.5~ up front ( + 4 inches from stock) and +4.5~ in the rear... (+6 :shock:

from stock in the rear)

Oh I'm running the stock 225/75r16's

Hub measurements

21 from center to the bottom of the fender up front and 23.5 in the rear

Sounds about right... My front coil overs are on their last legs and I have well over 300 pounds in the rear right now....

wolverine · **Posted:** Tue Oct 13, 2009 7:44 am

Yeah I forgot to mention that my measurements are with
an empty liberty and nearly empty gas tank

front coil overs on their last leg already?
Do you just do a ton of rough driving or is the
lifespan just that short?

Diggerfreek · **Posted:** Tue Oct 13, 2009 8:03 am

It is a design flaw of V1.0... I'll explain later

Diggerfreek · **Posted:** Tue Oct 13, 2009 11:12 am

Ok so in a nut shell, because of a design flaw with the very first PROTO type set of JBA UCA's, in combination with my driving, the UCA's trashed out the front coil overs because of contact made between the UCA's and the coil. Since the initial install, Marlin at JBA has produced a set set of production UCA's that have addressed the clearance issue. Also, a totally new coil over is being produced to also address the clearance issues. With the new set up, a 6 inch lift should be possible with out having the problems that I have had.

Once I get the OK from the higher ups, I will post up a complete failure analysis....

Now im going to be buying some JBA UCAs. Are the current KK ones on the site the new revised ones or the ones that have problems?

Wow it is nice to see non bashing about a failed prototype...
As wel all know test peices fail.. that is why they are test pieces....

lets just be happy it was tested...

bettsyboy · **Posted:** Wed Oct 14, 2009 12:51 am

with the Daystar 2" lift from the center of the rim to the bottom of the fender is about 20" in front and just about 21" in the rear, just about exactly what you measured +2"

I run 245/70R17's on the same stock 17" wheels you have in your pic

wolverine · **Posted:** Wed Oct 14, 2009 7:59 am

Thanks bettsyboy. So the daystar 2" lift does indeed lift 2"

congrats on the 2010 kk purchase.
How long did you even have it before changing out
the tires and lifting it?
