Achieve maximum traction with advanced locking differential technology.
The ARB Differential Carrier Air Locker is engineered for high-performance applications, specifically designed for Dana 70 and 80 axles. This locking differential features a 35 spline count and a highway high gear ratio, ensuring optimal performance on various terrains. Constructed from aerospace-grade alloy steel, the Air Locker is built to withstand extreme conditions while providing 100 percent traction on demand without compromising on-road drivability or driveline wear.
The innovative design incorporates forged gears and a two-piece construction that enhances strength and durability while minimizing moving parts. This results in a more responsive activation and increased load-bearing capabilities. The development process includes rigorous testing through Computerized Finite Element Analysis (FEA) to simulate extreme off-road conditions, ensuring that the Air Locker exceeds the strength of surrounding driveline components.
Field testing in harsh environments further validates the reliability of the ARB Air Locker, which is manufactured in Australia and backed by a five-year warranty. The user-friendly operation allows drivers to engage the locking mechanism without leaving the vehicle, making it easier to navigate challenging terrains. Installation and maintenance are straightforward, requiring no special tools or skills, making this product a practical choice for off-road enthusiasts.
