ARB Air Locker Differential
1994–2002 Dodge Ram 2500 / Dodge Ram 3500
RD170
Overview:
The ARB Air Locker is the world’s leading traction aid designed to provide maximum grip and control in challenging off-road conditions. Specifically engineered for Dana 70 and Dana 80 axles with 32 spline shafts, this low-speed Air Locker is an ideal upgrade for 1994 to 2002 Dodge Ram 2500 and Ram 3500 trucks. With the simple flick of a switch, the Air Locker instantly locks the differential, ensuring both wheels turn together for superior traction on slippery, rocky, or uneven terrain.
Perfect for off-road enthusiasts, overlanders, and work trucks alike, the ARB Air Locker enhances vehicle capability without compromising on-road drivability. When disengaged, it functions like a conventional open differential, providing smooth handling and reducing driveline wear during everyday driving.
Key Features:
Designed for reliability and ease of use, the ARB Air Locker offers a range of advanced features that set it apart from other locking differentials:
- Instant, on-demand locking with a simple dashboard switch
- Operates at any vehicle speed, allowing activation during low-speed maneuvers
- Pneumatically operated locking system that prevents internal differential gears from rotating independently
- Steel reinforced, elastomer bonded annular seal engineered to withstand extreme temperatures and harsh environments
- Two-piece ultra-durable design with minimal moving parts for maximum reliability
- Patented timed locking mechanism for high strength and rapid unlocking
- Provides 100% traction without affecting normal on-road drivability or causing driveline wear
- Includes activation switch, solenoid valve, air line, and bulkhead fitting for complete installation
Construction & Design:
The ARB Air Locker is built with robust materials and precision engineering to endure the toughest off-road conditions. Its two-piece design minimizes moving components, reducing the risk of mechanical failure and ensuring long-term durability. The steel reinforced, elastomer bonded annular seal is specifically designed to maintain airtight integrity under extreme climatic conditions, from freezing cold to scorching heat.
The internal pneumatic system engages the locking mechanism smoothly and reliably, allowing drivers to maintain control without interruption. This rugged construction makes the Air Locker a trusted choice for serious off-roaders and professionals who demand dependable traction solutions.
Installation & Fitment:
This Air Locker is a direct fit for Dana 70 and Dana 80 axles with 32 spline shafts on 1994–2002 Dodge Ram 2500 and Ram 3500 models. Installation requires an air compressor system (sold separately) to operate the pneumatic locking mechanism. The kit includes all necessary components for activation, including the switch, solenoid valve, air line, and bulkhead fitting, simplifying the installation process. Professional installation is recommended to ensure proper setup and optimal performance.
What's Included:
- ARB Air Locker differential assembly
- Activation switch for dashboard mounting
- Solenoid valve for pneumatic control
- Air line tubing
- Bulkhead fitting for secure air line routing
Ideal For:
The ARB Air Locker is ideal for off-road enthusiasts, hunters, farmers, and anyone who requires enhanced traction in challenging environments. It is especially suited for Dodge Ram 2500 and 3500 owners who frequently encounter mud, snow, rocks, or uneven terrain and need reliable, on-demand traction without sacrificing everyday drivability.
