JK 2.5" Lift

Postby jayhawkclint » Mon Mar 25, 2013 2:01 pm

Just bought new shoes for the JK. Going to try running a 285/75r17 KM2 on OEM aluminum wheels. Rolled the new tires up next to the old ones, just eyeballing I think I need about a 2.5" lift. Here are the two options I'm considering:

1) I really liked the quality of Fred's RK long arm kit on his TJ. Although a long-arm kit isn't in the budget right now, the quality seems to carry over to their less expensive kits. I don't know enough about the JK geometry to know how much kit I need. Looking at their 2.5" Flex kit and their 2.5" Max travel kit, the main difference being adjustable lower control arms. Are adjustable control arms going to be worth an extra $400 in a 2.5" kit?

2) Teraflex springs seem to be decently reviewed on some of the forums. The rest of their kit seems to be a piece of crap. They sell their springs separately and are very modestly priced. Thinking maybe get the springs and some Bilstein 5150 shocks, and build the rest of the disconnects and track bar bracketry myself re-using the factory lower control arms. Would this be a good solution, or am I going to have axle location issues due to short control arms?

You know I roll old-skool, this new-fangled coil stuff is rocket science to me, please edumacate me up.

We put rough country 2.5 on Gales. It did not come with lowers, and we have no known issues. It came with springs, shock extenders,and brake line extenders. It was cheap, but rides real well.

For that setup may just need a budget bust. Cheap and easy a 2" lift may look over kill

I went with rough country with 2.2 shocks on mine and their disconnects. It was cheap, rides ok. Will try something different next time to compare. In sure it's like everything else you get what you pay for.

Just trim out the fenders if that is all you need.

JK 2.5" Lift

Postby jayhawkclint » Thu Mar 28, 2013 9:55 am

After looking for hours at kit advertisements and install instructions, reading reviews, Googling pics of installed ride heights, reading about how shocks were too short in some or springs sagged in others or brake lines needed to be lengthened, etc, etc, I have decided to piece together my own "kit" using the following:

1) Rubicon Express 3.5 spring and adjustable track bar kit. Also comes with rear relocation bracket, brake line tabs, and a bunch of misc hardware.

2) Bilstein 5100 shocks for lifted JK with approx 11" of travel.

3) Teraflex braided brake hoses.

4) AEV front geometry correction brackets for JK.

5) Possibly some 1.25" spacers, TBD upon tire mounting.

"Kit" totals about $1200 shipped. When I added Bilsteins or brake lines or whatever else was missing from the other kits I looked at, this seems to be the less expensive route and more complete. I know it's more lift than needed for a 34" tire, but as I add bumpers, take into account spring sag, and larger tires/regear once it is no longer a DD, hopefully going to be a 1 time deal rather than nickel and dimed. There are 1.75" spacers on there now, and just rolling the tires up next to the old ones I would say 2.5" is the bare minimum I could get away with, so I'm basically adding an extra inch to account for future stuff.

Have never spent this much on the JK before, looking for inputs before I order. Thoughts?

Sounds good, just place the order and let me know when to come over so I can stand over your shoulder and tell you how to install it while I drink copious amounts of beer.
I used to own a Jeep, and it was cooler then yours.

Sounds like you have a good plan for your lift. Been through 2 to get where I am now. As for Pete, Mr.13, I will come by and guard the beer. He is a beer pig. I will also protect your Crown and Patron.

What can I say Geek, when my Jeep became a lawn ornament I started drinking heavy.
