The XRock adjustable antisway bar system from T&J Performance Center allows a Currie Antirock sway bar to be installed on '84-'01 Jeep Cherokee and Comanche vehicles.
The Antirock sway bar from Currie Enterprises is an adjustable sway bar that helps balance a vehicle's suspension - even on the trail. It's nearly become a staple on Jeep TJ and JK Wrangler suspensions, and with the new XRock system from T&J Performance, the popular Antirock sway-bar system can now be installed on Jeep Cherokee and Comanche vehicles.
One of the benefits in using a Currie Antirock-style sway bar is that you can hit the trail without having to disconnect your sway-bar links and still have maximum suspension travel at your disposal. The axle is connected to Heim-joint links that lead to adjustable arms connected to a torsion-bar spring that twists as the suspension flexes. Since the sway bar remains connected, the vehicle's suspension remains more balanced for all off-road driving situations. This helps in steep, rutted hillclimbs by keeping some of the weight of the front end from shifting to the rear axle as gravity takes over, and the front suspension unloads. With some weight still over the front end, the tires are more likely to find traction, and the rear axle isn't burdened with the whole job of cresting the hill. The cringe factor in off-camber sections is also lessened as the Antirock will help keep the weight of the body from rolling to the low side. The Antirock sway bar is also adjustable, so that one or both sides of the suspension can be preloaded to modify ride characteristics - both on the trail and on the highway.
The XRock from T&J Performance is designed to fit '84-'01 Cherokees and '86-'92 Comanches with 3 to 4 inches of lift. Vehicles equipped with aftermarket bumpers may need to cut or grind the bumper-mounting area to obtain the necessary clearance for the XRock mounting bracket. The XRock mounting system is manufactured from chrome-moly tubing and high-strength steel tabs and offers a simple bolt-on installation with no welding required. The crew at T&J Performance Center in Orange, California, installed the Antirock on an '86 Comanche to show us the process.
The XRock system consists of the XRock mounting bracket along with the appropriate-length torsion bar, arms, and links. All of the necessary hardware is included for an easy bolt-on installation. | 
The crew at T&J Performance began the installation by removing the factory sway-bar components and cutting off the factory horn mount behind the bumper. | 
The torsion bar and provided bushings were then inserted into the XRock tube-mounting bracket. |
