ARB RD157 Air Locker Locking Differential - Kit

The ARB RD157 Air Locker is a premium locking differential designed to deliver maximum traction in the most demanding off-road conditions. As the world's leading differential traction aid, the ARB Air Locker provides on-demand traction control that allows you to confidently navigate through mud, sand, snow, and rock crawling situations where open differentials would leave you stranded.

Key Features:

• On-demand activation allows normal driving on-road and locked traction off-road
• Pneumatic operation provides 100% power to both wheels when engaged
• Complete kit includes replacement differential housing with Air Locker mechanism
• Activation switch with LED indicator for cab-mounted control
• High-flow solenoid valve for fast, reliable engagement
• Air line and bulkhead fittings for professional installation
• Engineered and manufactured to OEM standards for reliability
• Compatible with existing ring and pinion gear sets

Unlike limited-slip differentials that provide partial traction or welded differentials that compromise on-road handling, the ARB Air Locker gives you the best of both worlds. Drive normally on pavement with an open differential for smooth cornering and tire wear, then engage full locking capability with the flip of a switch when the terrain demands it. The Air Locker's durable construction and proven design have made it the go-to choice for serious off-road enthusiasts, expedition vehicles, and professional rock crawlers worldwide.

What's Included: Air Locker differential assembly, in-cab activation switch, solenoid valve, air line, bulkhead fittings, and installation hardware.
