Off-road enthusiasts understand the critical role that differentials play in navigating challenging terrain. Among the myriad options available, one name stands out: the ARB Air Locker. Renowned for its durability, reliability, and ability to enhance traction in any terrain, the ARB Air Locker has become a staple in the arsenals from weekend warriors, to rock crawlers, to professional off-road racers.
Understanding Locking Differentials
Before we dive into the specifics of the ARB Air Locker, let's first understand the concept of locking differentials. In a typical open differential, power is distributed evenly between the two wheels on an axle. While this setup works well for normal driving conditions, it can lead to issues when one wheel loses traction. In such scenarios, power is directed to the wheel with the least resistance, often resulting in a loss of momentum and traction.
Locking differentials address this issue by essentially "locking" both wheels on an axle together, ensuring that they rotate at the same speed regardless of the conditions. This equal distribution of power maximizes traction and improves the vehicle's ability to traverse challenging terrain, such as mud, rocks, or uneven surfaces.
The ARB Air Locker Difference
What sets the ARB Air Locker apart from other locking differentials on the market?
1. Durability: Built to withstand the rigors of off-road driving, the ARB Air Locker is constructed from high-quality materials and engineered to handle extreme conditions. Its two piece case, forged gears, and timed locking mechanism makes it the strongest locking differential available.
2. On-Demand Activation: One of the standout features of the ARB Air Locker is its on-demand activation system. Unlike some other locking differentials that remain engaged at all times, the ARB Air Locker can be engaged or disengaged with the flick of a switch. Unlike other selectable lockers, the ARB Air Locker can be actuated at any speed as long as the throttle is not engaged. This versatility allows drivers to maintain optimal control and maneuverability in various driving conditions, switching between locked and unlocked modes as needed.
3. Air Operated: As its name suggests, the ARB Air Locker is operated using compressed air. This pneumatic system offers several advantages, including rapid engagement and disengagement, minimal maintenance requirements, and compatibility with onboard air compressor systems (a crucial piece of equipment for any 4x4). Additionally, the use of compressed air eliminates the need for complex wiring or hydraulic components, simplifying installation and reducing the risk of mechanical failure.
From the push of a button, air flows from the compressor to the differential. This compressed air pushes against a seal to drive the internal clutch gear which then locks the internal spider and side gears. This patented locking system only allows the locker to be locked in the strongest position possible, which increases the strength by up to 40%. Once locked, each tire begins to move at the same speed giving the vehicle equal traction when needed.
4. Compatibility: Whether you drive a Jeep Wrangler, Toyota Land Cruiser, or Ford Ranger, there's a good chance that ARB offers an Air Locker solution for your vehicle. There are over a thousand different Air Locker applications available across hundreds of vehicle platforms.
5. Proven Performance: Over the years, the ARB Air Locker has earned a reputation for delivering exceptional performance in the most demanding off-road conditions. From the deserts of Baja to the rocky trails of Moab to numerous Ultra4 and King of the Hammers victories, countless off-road enthusiasts rely on the ARB Air Locker to conquer obstacles with confidence.
The ARB Air Locker locking differential represents the pinnacle of off-road performance and reliability. With its durable construction, on-demand activation, air-operated design, broad compatibility, and proven performance, the ARB Air Locker is the ultimate choice for off-road enthusiasts seeking to unlock their vehicle's full potential.
Whether you're embarking on a weekend adventure or professionally tackling the toughest trails, the ARB Air Locker will get you where you need to go – and back again – with confidence.
