Johnny Joint Rod Ends
Johnny Joint Rod Ends
RockJock Johnny Joint Rod Ends are widely considered the gold standard for off-road suspension flex and durability. Originally designed to solve the limitations of standard heim joints and rubber bushings, the Johnny Joint offers superior articulation without the noise and harsh impact associated with metal-on-metal spherical bearings. Whether you are fabricating a custom 4-link suspension, building a long-arm kit, or simply replacing worn-out ends on your current control arms, these joints provide the reliability and range of motion necessary for technical rock crawling and daily driving alike. If you need help choosing between forged and weld-on styles for your custom fabrication project, please Contact Us.
Why this upgrade matters
The Johnny Joint’s design changed the off-road industry. Here is why it remains the top choice for suspension builders:
- Maximum Articulation: Provides up to 40 degrees of unrestricted movement in any direction, allowing your axles to articulate fully without binding the suspension arms.
- Vibration Dampening: Unlike a steel heim joint, the Johnny Joints use a high-density urethane bushing that isolates road noise and absorbs impact, resulting in a quieter, smoother ride.
- Greasable: All Johnny Joints are greasable via either a zerk fitting on the outer shell or internally via a gresable bolt. For maintenance intervals and step-by-step rebuild procedures, please consult our Instruction Manuals.
- Fully Rebuildable: These joints are designed for the long haul. Instead of discarding the entire unit when wear occurs, you can easily install an affordable internal rebuild kit.
- Severe Duty Strength: Forged steel and weld-on construction options ensure these rod ends can withstand the massive torque and shock loads of 40-inch+ tires.
