Default Steering geometry issue

Hi. My ride is a 2018 Rubicon JKU.
I mounted the 2inch Mopar lift kit. Great kit, no issues.
Then I mounted the Teraflex Monster Forged Track Bar and also the JKS flip drag link plus Track bar relocation bracket.
Now the drive is very stable
Problem: the Drag Link hit the mounting bracket body side when the suspension flexes.... big time. It actually feels like I am bottoming out...

what is the issue? Do I need to install bump stop extension? If so, why installing a lift kit and then reduce the suspension flex with extra bump stop?....
Thanks....

There are a number of 'Important Notes' listed in the description of the jks flipped drag link.

Requires 3" of front bump stop extension, JKS1130 available separately
Generally, people think about flipping when over 3", not 2", which helps to accommodate the added bumpstop. I have seen pics posted of chunks being cut out of the frame to give clearance rather than adding bumpstop, but I don't recall reading of anyone needing to clearance a bracket.

(If Dirtman doesn't see this and reply, send him a message.)

Generally, people think about flipping when over 3", not 2". If you don't want to add bumpstop, look into some cutting and welding on bracket, and even on the frame if you need to. (there have been quite a few pics posted of the cutouts made for clearance on the frame, so shouldn't be too hard to track down if no one else replies with more info)
Hi and thank you. Yes I noted. I am still wondering the logic into this . Mounting a lift kit to increase (amongst other thing) the suspension travel and then mounting a 3 inch bump stop extension yo limit the suspension travel...
Do you know of other mounting bracket extension that dont require longer bump stop?

Sorry I see now you mentioned cutting the bracket. I was going to have it done today... but then decided to look for more info in the forum before chewing in my frame...
Got it. Thanks a lot

Sorry about that, didn't think you'd be on and replying right away - I was going back and editing my reply as I was looking at that JKS bracket and draglink on their website. Hadn't seen those before.

But yeah, move the passenger end of the draglink up a couple inches, it's that much closer to the frame so makes sense that people are adding bumpstop or chopping into the frame on the passenger side. But your bracket on the driver side? Combination of low lift height and lack of bumpstop?

Agree. I was going to call JKS for more info. They say it fits lift from 2 inches and up. I wonder also if the shape of the teraflex drag link doesnt help. I will reinstall the factory one to see if the angle is better.
If not I will have my frame chopped a bit. Although I dont like the idea.
Also my current fox shock on the driver side, where the DL hits the frame, is dead. Not sure if a good shock will avoid the problem. I will go step by step.

One thing to keep in mind is that when modifying a vehicle, you're never going to have perfect situations. There are always tradeoffs along the way. You're lifting an jeep for offroad purposes, but then you're doing a high steer for on-road purposes. Those two things right there conflict with each other. It's easy to build a wheelin rig, it's harder to make it drive nicely on the pavement.
