rehashing 3.5" or 4" lift options for jeep liberty kj

Just about to order the JBA upper a arms and wondering; what exactly.would i need to lift a little higher than my current 3" without needing to buy machined cv axles? (Because i just put a couple thousand clicks on my new stock ones)

I have some upper isolators for the rear, ive read about a conduit nut for the clevis? Will i need longer brake lines?

Depends on what year you have as far as brake lines 05 later just a drop down bracket is needed
What lift do you have now?
You can gain 3/4 of an inch with a 3/8 inch clevis
Going to 4.10s with larger tires ?

03 no bracket needed for rear brake lines
If you have 927s in front do you have a top plate or anything else ?
Use 1/4 inch top plate for 1/2 inch lift, takes you to 3 inches, add a 3/8 inch clevis which will take you to 3.75, anything above 3.5 you'll have some UCA/ spring contact anyways so be prepared for that

Great!! Yes i do have the 1/4 top plate, will i get contact even with the new JBA upper a arms? with the clevis do i just go get a 3/8 spacer and put it on the bottom of the front shock?

All depends between 3.5 and 3.75 is where most get their contact ( yes even with JBA arms)

Most just use 3 inch conduit nuts - three of them at 1/8" thick equals 3/8" total, which will lift your KJ 3/4" of an inch. The conduit nuts go on the bottom of the shock between the bottom of the shock mount and the clevis. They are really just on there for spacing purposes; you can just lower the clevis 3/8", tighten the bolt down and leave it. Personally I like having the conduit nuts in there just in case the clevis bolt isn't tight enough - prevents it from sliding up. It's up to you.

If I were you - and you have the funds - I'd buy a set of JBA's upper control arms. Your alignment will be in factory spec and you'll HATE the banging from the stock upper control arm hitting the spring. It happens over even mild bumps - happened on mine and I quickly ordered the JBA arms and got them installed. Quiet as a church mouse now

Thanks guys! I didnt want to leave a void betwen the clevis either, this is what i was lookin for. Yes, i just lived with the contact on the springs. Ive been running this lift for over 20k clicks or so (wheeling it too!) And my tie rods and a arm ball joints all went at same time haha, mind you; there are over 260k km on the body of this one

Getting to the point now where i could have put in a SFA haha, wonder how easy a dana 30 would bolt up?

You're right - trying to type fast while on pain meds doesn't work.

Thanks for the correction

Merry xmas everyone!

So just still curious about the rear brake lines after doing the extra lift by adding a upper coil isolator; i have pulled my rear swaybar to eliminate the contact from the rear uca bracket bolt... will the extra flex cause any pull on the rear brake lines? Or is it fine at 3.75" of lift?

Thanks as always!
