ARB Air Locker Dana 30 27-Spline Locking Differential 3.73 & Up Ratio - RD100
$1,299.95
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1968-1971 Ford Bronco and 1971-2025 Jeep Cherokee, CJ5/CJ6/CJ7, Comanche, Grand Cherokee, Liberty, Scrambler, Wagoneer, and Wrangler.
The ARB Air Locker RD100 is a world-class traction aid designed for Dana 30 housings with 27-spline axles and gear ratios of 3.73 or numerically higher. Unlike automatic lockers or limited-slip differentials that can be unpredictable on-road, the Air Locker provides a 100% mechanical lock on demand. With the flick of a dash-mounted switch, the pneumatically operated system prevents internal differential gears from rotating, ensuring both wheels receive equal torque regardless of ground contact or surface conditions.
- Precision Engineering: Features a patented 'timed' locking mechanism for high strength and ultra-fast disengagement when returning to open-differential mode.
- Durable Construction: Built with a two-piece design that minimizes moving parts for maximum reliability in extreme off-road environments.
- Extreme Seal Performance: Includes a steel-reinforced, elastomer-bonded annular seal designed to maintain pressure across extreme temperature ranges.
- Complete Installation Kit: Includes the Air Locker differential, pneumatic solenoid valve, activation switch, air line, and bulkhead fitting.
- Required Equipment: An on-board air compressor is required for operation (sold separately).
- Manufacturer Part Number: RD100
