Skyjacker’s RockLock Unlocking Swayber for Wranglers is Like Two Sway Bars in One

    Skyjacker Keeps the Sway at Bay

    For years we ran sway bar disconnects on our 2006 LJ Wrangler with 35-inch-tall tires. The disconnects provided stock handling on the street with uninhibited articulation on the trail. They were a chore to get aligned at times, but that was considered a small price to pay. It wasn't until we moved up to 37-inch-tall tires and they rubbed the sway bar at full lock that we started to look for a better alternative.

    That better alternative is Skyjacker's RockLock selectable front sway bar. The RockLock is a torsion bar-style sway bar with flat endlinks that provide more tire clearance than the factory sway bar. Unlike other torsion bar-style sway bars, Skyjacker's RockLock uses a splined hub on one end that allows it to be disengaged with the simple twist of the dial, just like unlocking an axle hub. It might not be as fancy as the in-cab disconnect available on the JK and JL Rubicons, but it is light-years ahead of traditional sway bar disconnects. No more rolling around on the ground lining up holes and pins.

    Skyjacker includes everything you need to replace the factory sway bar on your Wrangler. Rather than a one-piece bar that curves on the ends, Skyjacker uses a straight torsion bar with arms that spline onto the ends and a hub to easily disconnect the sway bar.

    Those aren't the only benefits, though. The Rock Lock also has three different mounting hole options on the arms. The farther forward on the arms you mount the endlinks, the effectively shorter the arms are. This increases the resistance on the road, resulting in a stiffer sway bar. We made the bar as stiff as possible since we are running relatively soft Skyjacker dual-rate coil springs, but you can fine-tune the sway bar stiffness to best complement your specific suspension on your 1997-2006 TJ or LJ Wrangler.

    The RockLock installation only took us a couple of hours with handtools, and the result met our goals by being easier to connect and disconnect and increasing tire clearance. After thousands of miles and numerous trips over the Rubicon we could not be happier in the improvements both on- and off-road.

    The factory sway bar bows out to make a smooth bend beyond the framerails. As a result, it sticks out farther than the Skyjacker Rocklock sway bar, which has splined arms that attach to each end of the bar. The extra clearance was critical for our application.
    Our old sway bar disconnects did a fine job of providing control on the pavement and lots of articulation on the trail. They could be a challenge to reconnect at the end of the trail, though, particularly if we were not on flat ground. The biggest issue was that running 37-inch tires with factory-width axles resulted in the tires rubbing the sway bar at full lock.
    Skyjacker includes detailed instructions with the RockLock, including photos. We found the hub assembly to be the most complicated part of the installation, and even that was straightforward with the instructions on hand for reference.
    Rather than going over the top of the frame, the RockLock fits inside the front crossmember and is centered using two Delrin pucks. The pucks have a flat spot on them that matches the crossmember and keeps them from spinning in the tube. Note that there are different pucks for the driver and passenger sides; they are not the same. The thicker puck goes on the driver side.
    The only issue we ran into was that the hub on the RockLock was too large to fit in our aftermarket Warrior Products front bumper. We didn't even remove the bumper; we just used a crescent wrench to bend the bumper out slightly and create the necessary space for the hub. Now the hub is well protected from impacts behind the bumper.
    The splined hub is what separates the RockLock from other torsion bar-style sway bars on the market. You can still completely disconnect the bar on the trail for unhindered articulation, but with the twist of a dial you can reconnect the sway bar for street use.
    Skyjacker includes different length endlinks to accommodate lift heights from 2 inches all the way up to 10. The longer 10-inch links are recommended for 6- to 10-inch lift heights. The shorter 7 1/2-inch links are recommended for 2- to 4-inch lifts. We are running Skyjacker's 2 1/2-inch dual-rate coils, so we cut down the shorter endlinks and used the included rod ends and jam nuts.
    After the installation, check travel on suspension to ensure clearance on all parts. Make sure the endlinks are adjusted so that the arms are not in danger of flipping forward at full droop when the arms swing down.
