Product Details

The ARB RD164 Air Locker is a premium locking differential designed to deliver maximum traction in the most challenging off-road conditions. As the world's leading traction aid, ARB Air Lockers provide 100% power distribution to both wheels, ensuring you maintain forward momentum through mud, sand, snow, and rock crawling terrain where open differentials would leave you stranded.

Complete Air Locker System Includes:

  • Complete replacement differential with integrated air locking mechanism
  • Dash-mounted activation switch for on-demand engagement
  • Heavy-duty solenoid valve for reliable air control
  • Professional-grade air line for connection to onboard air system
  • Bulkhead fittings for clean, leak-free installation

ARB Air Lockers engage and disengage with the flip of a switch, allowing you to run unlocked for normal driving conditions and lock both wheels together instantly when maximum traction is needed. This on-demand functionality preserves drivetrain components and maintains street manners while providing unmatched capability when the terrain demands it.

Engineered and manufactured to exacting standards, ARB Air Lockers are trusted by serious off-road enthusiasts, expedition vehicles, and competitive rock crawlers worldwide. The system requires an onboard air source (compressor) for operation.
