Master Any Terrain with ARB

The ARB Air Locker is the industry-leading traction aid for off-road enthusiasts. This specific model is tailored for Dana 30 axles utilizing 27-spline shafts and gear ratios of 3.54 and numerically lower. If you are running taller gears in your classic Ford Bronco or Jeep, this locker is the essential upgrade to keep you moving when the trail gets tough.

Technical Advantages

• Pneumatic Locking: Uses an air-actuated piston to lock the differential, providing 100% traction to both wheels.
• Rugged Construction: Built for durability in extreme environments, ensuring long-term performance.
• Seamless Transition: Easily switch between open differential for highway driving and locked for technical trails.
• Improved Control: Allows for slower, safer navigation over rocks and uneven surfaces by maximizing tire contact.

When you engage the ARB Air Locker, you eliminate the power loss associated with open differentials. By locking the internal gears, the system ensures that both wheels rotate at the same speed, regardless of surface conditions. This provides the confidence to tackle obstacles that would otherwise leave you stranded. Whether you are building a dedicated trail rig or a weekend warrior, this differential is a cornerstone of off-road capability.
