TeraFlex's #1600440 Flip Drag Link kit lowers the front roll center axis with that trackbar drop bracket. You have a front and rear roll center axis, both need to be on the same plane or the front lower for better handling. Raising the trackbar off the axle raises the front roll center.

 

So if I read that right, with your kit I'm ok roll center wise not having a drop bracket in the rear? If anything it might be better ride with a frame bracket in front and just adjustable TB in rear?

 

In the rear, it it's always better to have a axle mounted trackbar bracket. A rear adj. tb only recenters the axle, it doesn't help correct the geometry.

 

Poppy cock! You can't figure out the true geometry without knowing both! Just pure poppy cock!

This might sound weird after I just jump all over TeraFlex, but if it were my Jeep and those were the only two I was looking at, I'd go with the TeraFlex. Not because it lowers the roll center which it does, but because the AEV one raises the roll center. With the AEV if you don't address the the rear you could end up with a higher roll center in the front.

It's a Jeep, raising the roll center can be a good thing.

 

My rear TF axle bracket raised the Trackbar, plus I have their new Monster adj TB in the rear. Now being as that my front and rear are basically at the same angles(opposite of course) and both centered, I'd say my geometry is pretty good. Hell, it rides and handles well anywho. I'm not a geometricision

 

That's good to hear, this is my first build and all this time I thought the rear tb bracket was just to recenter the axle while using the stock tb. Thanks for the advise. I got rid of my frame bracket in the rear when I installed the jks tb....I guess I'll order an axle bracket along with what ever I end up choosing for my front issues.

 

I would also suggest that you get a new pitman arm nut if you remove the old one for any reason. In the work I do that is standard procedure. And be sure and torque it to spec.

 

Looks like I did a poor job on explaining myself there.I'll correct that post.
