JBA 4" lift

Does anyone have the JBA 4" lift? Wondering how they liked it. And what size tire would fit and if it would hold up to a ARB bumper?

4 inch lift = 265-75-16 tire

I can put that size tire with the OME lift. I wish I lived closer to you. Not that mechanically inclined to put a lift on. :JEEPIN:

going bigger than 265/75/16 on the D30A frontend is a reliability concern and a gearing problem.

Tokyojoe has the 4" lift - it looks good
there was a post about trying to get the CV's trimmed - it became a major issue - so buying the kit with the CV's is a good idea.

you can go that high pretty much with Frankenlift / or OMEs with extras.
But with the gearing we have available, the weak D30a etc you don't really want to go bigger anyways

I think I will stick with my original plan and go for the OME lift. I want to put on 265/70/16. :JEEPIN:

The Reverend did 265/75R16 with his custom OME.

265-70s are easy with OME etc. Its a good size, don't loose much power/mileage ( like when going to 265-75s)
Good choice!!!

Thats what I meant 265/75/16. Will the Ome lift be enough or am I going to do anything else? :JEEPIN:

if you said Mudd has Mud Flaps - the alliteration would have added to the impact, and generated at least a few puns...........

you have to add stuff - Clevis + top spacer ect. - basically you get about 2 1/2" - 3" of of OME - depending on the spring rate - but you can tweak things a bit to get enough clearance for 265/75's

Yes have to do all of the above to make sure you have enough room to run them with OME 927s
also get ready for less power, running with the OD off more, less mileage, I dropped about 2 MPG when I went to 265-75s from 265-70s
of course all of the above if you don't go to 4.10s right away.
Love the look but if I had to do it over again.........

Tom,

Is yours taller than 03's?? It looks like it in that pic.

Also, where is your spare?

I had the spare off waxing behind the tire holder, do that a couple of times a year!

At that point he had just the Frankenlift on, I had just replaced mine with new rear 948s and two extra top isolators
Of course also I have 265-75s and he has 245-75s so some difference

BUT YES I WAS (AND AM) TALLER :ROTFL:

TexasRock, that was the best thing you could have EVER said to Tom

im just kidding Tom

i hate the back bumper area, it collects like 50lbs of mud back there and is a pain to clean it out. i might do your bumper cut mod just for that reason

Why?
Yeah I (the KK owner) have wondered over to the KJ area for help. On one with 265/75r16 over in the KK section. Got one with 33's but he re-geared before the tires. Are the KJ gearing the same? I have the auto 3.73. Just got the 4" JBA lift and wanted 32's but seems like people say I will loose WAY to much power and won't like it. And to re-gear. Re-gearing I found out is very labor costing $825 quoted today by ORU plus gears which are ?? So my question I tow about 4-7 times in the summer about 2200# from LA area to Laughlin up some nice climbs. I did it once so far stock and it was last year but think I remember only one hill out of Needles, CA on hwy 40 I was stuck at 55-60 mph. So with 265/75r16 how much power will i loose? I take it power loss is from the height not width as 235/85r16 won't be better. Well I thought a boat was a hole that you just thru water into, but seems like my 4x4 is a big boat! I could go 245/75r16 but and not re-gear nor need a tire gate also $700 for that. Thanks for any input my KJ friends.

Taller Tire = more weight
Taller Tire = more power loss
4” Lift = more wind resistance

Add those up and you will see a big loss in power and a significant drop in fuel economy. Gearing is one method to help compensate for the taller tire. Without adequate gears, your Jeep will be down-shifting a lot which will be hard on the transmission. It might seem expensive, but you wont fully enjoy your Jeep if you don’t do it.
