RockJock's Antirock Sway Bar Kit for the rear of all 2021-up Bronco vehicles helps free up suspension articulation to increase off-road traction. By constantly providing resistance to the articulating wheel, the Antirock forces traction to opposite wheels. The Antirock sway bar easily bolts on with hand tools, directly replacing the vehicle's stock rear sway bar. The Antirock does not require disconnecting for off-road use! The sway bar torsion bar is forged from 4130 heat treated chromoly for ultimate strength, which is the same quality used in professional off-road competition sway bars.

We have worked with AFE to create a simple to install, high clearance piece under item number 49-43147, however other exhaust manufactures likely produce compatible systems (Slide 7 in the photo gallery for a dimensional diagram). Body Roll
- Antirock sway bar equipped vehicles will exhibit more body roll than vehicles equipped with the stock sway bar. Antirock sway bars may be used on the street, however, they do not provide the same handling characteristics as the stock sway bar. End Links
- Out of the box, the length of the sway bar's vertical links that are included in this kit are intended for use with stock height vehicles. Depending upon your specific vehicle's lift, you may obtain shorter or longer links to suit, here. Additionally, all of the link rods may also be trimmed in length for fine tuning purposes. Fitment
- It is quite common for factory frames to vary in width. If you find your vehicle's frame to be on the narrower side, the Antirock arms can simply be slid on until they are snug against the Antirock bushings and then the arms clamped down. However, on some frames the arms absolutely have to hold true width to clear bolt heads on the side of the frame, etc. In instances of this nature, see our CE-9901D-SP4 shim pack to assist in fine tuning.
