My TJ is just about three years old, and I have been wheeling in it since the very beginning.   I initially installed a Rubicon Express 4.5” lift, and recently upgraded to their new 5.5” Long Arm lift.   Each of these kits came with Rubicon Express swaybar disconnects, as most lift kits for TJ’s do.

  While discussing the Long Arm kit with Rubicon Express, it was recommended that instead of installing regular old disconnects, that I ditch the stock swaybar and install the Currie Anti-Rock system.   This swaybar system has been around for over a year, and many Jeepers with whom I interact regularly really like the characteristics of their TJ after installing the kit.   So I called up Currie and had one shipped out.

The Anti-Rock is designed to help balance out the TJ off-road.   With a tall lift, and the front sway bar disconnected, the frame and body of the TJ will tend to move with the rear axle as the axles flex and move over terrain.   Why?   Because the rear swaybar is doing its job and keeping the axle and frame moving in relation to each other.

On-road, this is a great feature, as it keeps body roll to a minimum and provides for a stable drive.   Along with a front sway bar, the on-road stability is super, even with a tall lift.   But we all know that for maximum performance off-road, the front axle should be able to move freely from the frame.   Once we disconnect the front swaybar, the rear pretty much controls where the body moves.

The beauty of the Anti-Rock is that because it’s sway bar is so flexible, the front axle can remain connected to the frame, yet the axle is still allowed to move very freely over the terrain.   This causes the rear sway bar to work in conjunction with, yet against the forces of, the front sway bar.   The result is the body remaining more centered over the axles as one droops to the left and the other to the right.
