Longer brake lines with sway bar disconnected?

I just installed JKS quicker disconnects on my jeep last night. I'm very satisfied with them so far. The install went great. (With a couple minor problems of course lol) The only area i'm concerned with is the length of my brake lines. I have a 2.25 inch BB installed. Will the brake lines be long enough to handle a full flex when my links are discoed? I read on another forum that the stock lines are long enough to handle a full axle drop up to a three inch lift. Is this correct? Thanks in advance.

Lift jeep up. Drop front axle to full droop. Turn your wheels to full lock in one direction.

Are the brake lines tight?

If so, you need longer brake lines.

I'll say no. But I could be wrong.

Mine has a 2.5" OME lift on it. Here's a video of full flex and what the brake line looks like. They are fine for now, but I'll have to buy longer ones when I replace the control arms because I'll have more down travel.

Wow couldn't have asked for anything better than a video. So it seems like i should be alright. Thanks for the help. BTW that looks like a pretty sweet spot for wheeling from what I could see in the video.

if you watch that video closely, he never sees full droop and full lock turn to the left at the same time.

the brake lines approach tightness around 2:37, and the axle isn't even drooped much. at 1:03, the brake lines are tight, and the wheel isn't turned much at all.

Test it out like I suggested. only way you'll know, and you'll learn something.

You don't need longer brake lines for only a 2" BB lift with the front antisway bar disconnected. It's not even close to needing them.

Thank you Jerry. All information i've ever read from you before has been right so i have no doubts that you are right again, but i might still do as unlimitedLJ suggested just for the heck of it. Once again thank you all for the info/advice.

Since I have all the pros in one place. With 2.5 suspension and 1.25 body. Does the body lift effect the necessary length of brake lines?
