About Rockjock
RockJock is a leader in the off-road aftermarket, offering premium suspension, steering, and drivetrain components engineered to handle the toughest conditions. Built for Jeep Wrangler, Gladiator, Ford Bronco, and custom off-road builds, RockJock products are trusted by enthusiasts who demand durability, performance, and reliability both on the trail and on the street.
At the core of the RockJock lineup are the legendary Antirock sway bar systems, designed to balance stability and articulation for ultimate off-road control. These sway bars allow your vehicle’s suspension to move freely over rocks, trails, and obstacles while maintaining predictable handling on-road. Pair them with Johnny Joint control arms—RockJock’s exclusive high-misalignment, greasable flex joints—for improved suspension travel, reduced wear, and longer-lasting performance compared to factory rubber bushings.
For those upgrading drivetrain strength, RockJock offers heavy-duty differentials, axles, and gear sets that deliver the confidence you need when running oversized tires or pushing your rig through extreme terrain. Their precision-engineered steering components ensure tighter handling and more responsive control, whether you’re daily driving or tackling black diamond trails.
Every RockJock product is designed, tested, and proven by off-road experts, making it a top choice for rock crawling, desert racing, overlanding, and trail exploration. With a focus on American-made quality, RockJock continues to set the standard for performance suspension and drivetrain upgrades.
