Hi,
There are several brackets made to raise the axle mount of the rear track bar.

Are there any brackets made to lower the mount on the frame?

I have been looking at the clearance under the rear passenger quadrant and it seems like the nearest conflict might be the rear sway bar. I am wondering if anyone has tried lowering the mount and figured out if it is possible to do so without creating conflicts.

Thank you.

I haven’t seen or heard of one you can buy…. But this guy fabricated one for Kevin…… go to the 9 minute mark if you don’t want to listen to all the bullshit….also Kevin has anti rock sway bars.



I have a frame side reinforcement bracket on mine ( which I highly recommend) and my sway bar hits it at full stuff. It doesn’t hinder flex but there’s contact…….Antirocks are probably in my rigs future, but it’s not at the top of my list…..

I've yet to see anything that lowers the frame side. Safely assuming that this conversation is based on a lifted Jeep, the 2 main advantages of any track bar brackets are to raise the rear roll center and to add structural support to the track bar mounting points.

Lowering the frame side would be counterproductive to roll center, and if not designed correctly, would only give the axle more leverage for unwanted frame movement. The latter would result in a more mushy and unsure feel between the frame and axle, which would also translate to increased steering corrections.

The video posted by Roky is the only frame side relocation that I've come across. That's partly why I assumed this is about a lifted Jeep. Typically, it takes increased suspension travel before the driveshaft is flexing into the fuel tank.

Lowering the frame side has the same effect on the roll center as raising the axle side by the same amount. The roll center is the point at which a straight line between the mounts intersects the center line of the vehicle. Bends in the bar do not effect roll center. We ran this superlift frame side bracket on our 2019 with 3” of lift and 38’s for 50k miles, wheeled it all over the counrtry, and never had an issue. At 3” lift the axle was centered with the stock track bar.

I might be reading this incorrectly, but it looks like your first sentence contradicts the second. Axle side extensions raise the roll center, chassis side extensions lower it.

OP: consider a bigger rear swaybar to compensate for the extra roll.

At 2”-3-1/2” of lift height, roll center is minimal, some wouldn’t even notice. I’ve found with lifts of this height, it’s more important that the bar is level as opposed to being high…. The 4.5”-6” lifts will benefit from raising and leveling….. People say I need to raise the track bar to help with roll center that’s only because you need to raise it to get closer to frame side height…. If you left the axle side where it is and lowered the frame side so it’s closer to level, it will have the same affect, which is not much on these shorter lift heights…….

I opted to raise the axle side to level out the rear track bar. For the frame side, I added a straightforward reinforcement bracket. If all else is the same, I'd rather avoid giving the axle more leverage over the frame by extending that attachment point.

I knew beforehand that leveling the track bar would improve drive ability by lessening tail wag and whatnot. The unexpected but welcomed improvement was how drastically solid and planted the rear would feel. So much so, that it translated to a huge decrease in steering corrections (no real complaints beforehand) and increased ability to hold a line in the straights and curves.

A level panhard bar is definitely ideal, but the higher roll center will have a similar effect as a stiffer swaybar (even if it is just a slight effect). Actually... a closer description would be similar to lowering the center of gravity.

Unlike a stiffer swaybar, the higher roll center can't influence flex.

Agreed…….my track bar is almost dead level…..my track bar bracket is for 2.5, 3.5, and 4.5” lifts….. I’m on a 3.5 lift and moved it up to 4.5” lift setting, I did not notice any difference, but I like how level it is now better…..

Hi @Roky

Did you drill the extra mounting holes in your bracket or was it store-bought with the 3 choices?

It came that way, it’s part of the Rock Krawler long arm kit I installed…….. you cut off the shock/lower control arm brackets, track bar bracket, and weld on new ones, along with the truss for the single upper control arm……

Thanks.

Now I can recognize it in the pieces parts photos of the long arm kits on the RK website.
