ok i thought it was kinda weird...
but will i need long arms? or longer
break lines? or anything like that?

 

The TF 2.5" kit comes w/brake line lowering brackets, and other 3"-4" kits come with extended brake lines. So, I'd assume you would need to take care of this issue at your 4" benchmark. I don't know if the TF brackets would be enough to do this.
(you must know I'm a noob; all info comes from reading)

 

hey i thought that also but i have pm a few ppl and they have said different
things each times so im just get an over all response. but thanks a lot and i might just add the brake lines to be safe then sorry.
thanks for the help

Here's a pic showing what typically comes in a TeraFlex BB kit.

 

I guess only rear brake line drop brackets are included with Teraflex. Per the installation guide, "10. Install the lowering bracket for
the rear brake line with the supplied
hardware."

 

You could make your own for the front or rear by using a 1"x 3 or 4"x 1/8" aluminum that you can get at any hardware store. Drill a couple holes, take and relocate your line farther down. Use the stock bolt for the top and get a small nut and bolt where you relocate the line. Also slack can be pulled for the abs line by unclipping some of the mounts .

Here is the answer from the FAQ:

https://www.jk-forum.com/forums/modified-jk-tech-2/modified-tech-faq-answers-questions-every-newbie-has-18617/

Q: What are all the components that I will need with a 4" lift?
A: For a 4" lift, you should have a set of 4" coils, bump stop extensions, longer shocks, extended brake lines, longer sway bar links, adjustable front track bar, adjustable rear track bar, front and rear track bar relocation brackets, dropped pitman arm, adjustable upper and lower control arms front and rear and new double cardin u-joint style drive shafts.


Which TeraFlex lift kit do you have? Is it the kit that TeraFlex posted?

If so, you'll have a total of +/- 4.5" of lift, and :
-New rear links. (you will move your stock rear links up front)
-Front and rear 2" ext bumpstops (may not be enough with 4.5" of lift)
-Rear trackbar bracket for a 2.5" kit, so your rear axle won't be centered for your 4.5" lift.
-No front trackbar bracket/bar. (you will want to address this)
-Rear Brake line extensions for a 2.5" lift. (check the tightness during flex. You might look at extended lines also)
-No front brake line extension/line. (you will want to address this)
-Stock Control Arms. This means you have no way to adjust your caster. With a 4.5" lift, your handling will likely be very flighty, lots of bumpsteer, etc. (If so, look into at least a set of front lower adjustable control arms)
-Shocks? Do you have new shocks? Using shock extensions? The added 2" from lift spacers means you really need new, longer shocks)
-Driveshafts. Put some money aside for new shafts.
-what did I miss?

What size tire are you going with?
Have you looked into backspacing?
Are you prepared to 'trim' whatever rubs?
Have you considered the costs of re-gearing for the new tire height?
A programmer to reset your computer for the new tires/gears?

And the list just goes on and on...

 

hey i already have the spacer kit from skyjacker i'm looking at you
JK Wrangler 2.5” Lift Kit (SKU: 1351000) and i'm gonna fit the shocks once
i get everything installed and see which ones i need

 

You don't lower the t-case, but getting above 3" or so you will need to chuck the stock CV drive shafts and replace them with U-joint style.
Front for sure... Rear for sure on a 2dr... the longer rear on the 4dr can get away with a little more lift before having to replace it.
