Take Control of Traction When It Matters Most

When you're crawling up a rocky incline or powering through deep mud, the last thing you want is a tire spinning freely while the other just sits there. That’s where the ARB 9.5 inch Air Locker comes in for your 2022–2025 Toyota Tundra. This isn't just another upgrade; it’s a serious tool for anyone who demands real off-road capability. With a flip of a switch, the Air Locker transforms your differential from an open diff into a fully locked unit, forcing both wheels to turn together no matter the terrain under each one. This means maximum traction right when you need it, whether you're rock crawling, navigating snow-packed trails, or recovering from a sketchy hill climb. Unlike some locking systems that are always on or require wheel slip to engage, the ARB Air Locker gives you control. It locks instantly, even while moving, letting you focus on driving rather than fighting the trail.

Built Tough and Engineered for Reliability

The ARB Air Locker is built to take a beating. Its two-piece housing is precision-machined for strength and longevity, and the internal components are engineered with minimal moving parts to cut down on wear and tear over time. The locking mechanism is pneumatically controlled using air pressure, offering reliable engagement without relying on electronic sensors or clutches. A steel-reinforced, elastomer-bonded seal is built to handle the harshest environments—freezing temps, desert heat, and everything in between. ARB includes the differential itself, activation switch, airline, solenoid, and bulkhead fitting, so you're not piecing this kit together. An onboard air compressor is required to run it (sold separately), but the install is well-supported and worth the effort if you're serious about off-road capability. Compared to the stock open differential, this setup completely changes how your Tundra behaves when the terrain turns rough, giving you more confidence, better control, and the ability to push farther into the unknown.
