I have this kit and drives great without a flip kit. I have thought about it but just don't feel it's necessary.

Default Jam Nuts

If your asking about adjusting the control arms on the jeep. The instructions give you measurement to set the control arms to before installing them. Mine were dead on. If you have any other questions shoot me a message.
My front lower control arm Jam Nuts are into the axle bracket, so I have to remove them from the axle and let it swing down to be able to get a wrench on Jam Nuts. This does not seem correct... any thoughts?/?

I have the correct angle set. I found when I started mine the axle was set incorrectly.

Can you post a pic. I can do the same.

If you have any doubts on the wheel / tire combo just get the tire dealer to mount one wheel tire that you choose and test it on both sides of the front axle to see if it rubs anything before you pay for anything. If they want to make the sale they will at least mount one for you unless the wheel is an order only item.
You are going to love the 2.5 x factor. 35 x12.50's will rub a little on the back of the rear wheel well inner fender. I think I will end up trimming my fenders but think the pinch seam in the front of the rear wheel well is going to be ok.

Default Brake lines

New question about the front brake lines that came in the 2.5 max kit. I think they are these.
Wrangler JK Brake Lines
The bracket that mounts to the frame is the same for both sides. Which seems to make it backwards and opposite for one side. Hard to explain put on the passenger side it is orientated with the brake line hole on top and the frame mounting hole on the right (towards the front). Everything lined up good and fit nice. On the drivers side, it mounts and lines up poorly. With the bracket orientated with the brake line hole on top and the frame mounting hole on the right (but towards the back in this case), the hard brake line connection is to far away. Same issue if I flip it with the bracket orientated with the brake line hole on bottom and the frame mounting hole on the left (towards the front), he hard brake line connection is to far away. I try to get pictures as this seems difficult to explain clearly.

Can't you just remove the end you want to work on and let it hang down and tighten the jam nut then just push it back up into place?
