ARB Air Locker RD254 for Select 2003-2020 Dodge/Ram 2500/3500 & Nissan Titan (AAM 9.25/9.5, 33-Spline)

Fits select 2003-2020 Dodge/Ram 2500 and 3500, and 2016-2019 Nissan Titan and Titan XD models equipped with AAM 9.25 or AAM 9.5 axles. The ARB Air Locker RD254 provides 100% traction on demand, allowing you to bridge the gap between street drivability and hardcore off-road performance. Unlike automatic lockers or limited-slip differentials, the Air Locker operates as a conventional open differential for road use, preventing tire scrub and driveline bind. When engaged via the dash-mounted switch, it pneumatically locks the internal gears to ensure both axle shafts turn at the same speed, delivering maximum power to the ground regardless of terrain.

• Authoritative Design: Ultra-durable two-piece construction with minimal moving parts for maximum reliability in extreme environments.
• Timed Locking Mechanism: Patented system offers high-strength engagement and ultra-fast unlocking when traction is no longer required.
• Advanced Sealing: Steel-reinforced, elastomer-bonded annular seal designed to withstand extreme thermal cycles and high-pressure pneumatic operation.
• Kit Includes: Air Locker differential (RD254), activation switch, solenoid valve, heavy-duty air line, and bulkhead fitting hardware.
• Requirement: Requires an onboard air compressor for operation (sold separately).
