ARB Airlocker Dana 60 HD 35 Spline 4.56 Up: Dodge Ram 2500 / Ram 3500 1994-2003
ARB Air Locker Dana 60 HD Differential
1994–2003 Dodge Ram 2500 / Dodge Ram 3500
RD166
Overview:
The ARB Air Locker Dana 60 HD 35 Spline 4.56 Up is a premium pneumatic locking differential designed to deliver maximum traction for your Dodge Ram 2500 and Ram 3500 models from 1994 to 2003. Engineered for off-road enthusiasts and professionals alike, this Air Locker provides instant, on-demand locking of the axle shafts, ensuring both wheels turn together for superior grip in challenging terrain. With the simple flick of a switch, drivers gain confidence and control, enabling safer, more efficient navigation through mud, rocks, snow, and other low-traction conditions.
Unlike traditional limited-slip differentials, the ARB Air Locker offers 100% lock-up capability without compromising on-road drivability. When disengaged, it functions as a standard open differential, preserving smooth handling and minimizing drivetrain wear. This makes it an ideal upgrade for Dodge Ram owners seeking enhanced off-road performance without sacrificing everyday usability.
Key Features:
Designed with durability and reliability in mind, the ARB Air Locker incorporates advanced technology to ensure consistent performance in the toughest environments:
- Instant pneumatic locking system activated via a simple dashboard switch
- Operates at any vehicle speed, allowing activation on the move
- Steel reinforced, elastomer bonded annular seal for extreme temperature resistance
- Minimal moving parts for maximum reliability and reduced maintenance
- Patented timed locking mechanism for high strength and rapid unlocking
- Provides 100% traction on demand without affecting driveline wear or on-road handling
- Two-piece ultra-durable design engineered for heavy-duty Dana 60 HD axles
- Compatible with 35 spline axle shafts and gear ratios of 4.56 and up
- Includes all necessary components for installation, including activation switch and air line
Construction & Design:
The ARB Air Locker is built to withstand the rigors of off-road use and harsh climates. Its two-piece design features robust steel construction combined with elastomer bonded seals that resist wear and environmental damage. The internal locking mechanism is pneumatically operated, eliminating the need for complex mechanical linkages and reducing the risk of failure. This design ensures smooth engagement and disengagement of the differential lock, even under load and at varying speeds.
Precision engineering and quality materials make this Air Locker a dependable upgrade for the Dana 60 HD axle, known for its strength and durability in heavy-duty Dodge Ram trucks. The unit’s minimal moving parts reduce potential points of failure, providing long-lasting performance with minimal maintenance.
Installation & Fitment:
The ARB Air Locker Dana 60 HD is a direct-fit replacement for the differential in 1994 to 2003 Dodge Ram 2500 and Ram 3500 trucks equipped with 35 spline axles and gear ratios of 4.56 and higher. Installation requires an air compressor system (sold separately) to operate the pneumatic locking mechanism. The kit includes all necessary hardware, such as the activation switch, solenoid valve, air line, and bulkhead fitting, to facilitate a straightforward installation process.
Professional installation is recommended to ensure proper setup and integration with your vehicle’s existing drivetrain and air supply system. Once installed, the Air Locker allows drivers to engage or disengage the locker from the comfort and safety of the driver’s seat, enhancing convenience and control.
What's Included:
- ARB Air Locker differential unit for Dana 60 HD axle
- Activation switch for in-cab control
- Solenoid valve for pneumatic operation
- Air line and bulkhead fitting for air supply connection
Ideal For:
This ARB Air Locker is ideal for Dodge Ram 2500 and 3500 owners who demand superior traction and reliability in off-road conditions. Whether you’re tackling rocky trails, deep mud, snow, or uneven terrain, this differential upgrade provides the confidence and capability needed to keep moving forward. It is also well-suited for work trucks requiring enhanced traction for heavy loads and challenging job sites, without sacrificing on-road drivability.
