ARB Air Locker Differential
1994–2002 Dodge Ram 2500 / Dodge Ram 3500
RD171
Overview:
The ARB Air Locker is the world’s premier traction aid designed to provide maximum traction on demand for off-road enthusiasts and professionals alike. Specifically engineered for Dana 70/80 axles with 32 splines, this high-speed Air Locker is an ideal upgrade for 1994 to 2002 Dodge Ram 2500 and Ram 3500 models. With the simple flick of a switch, the Air Locker instantly locks the differential, ensuring both wheels turn together to maintain traction in the most challenging terrain.
Designed for drivers who demand reliability and control, the ARB Air Locker allows you to tackle mud, rocks, snow, and uneven surfaces with confidence. When disengaged, it functions as a conventional open differential, preserving smooth on-road drivability and minimizing driveline wear.
Key Features:
ARB Air Locker’s innovative design offers a range of advanced features that enhance vehicle capability and durability:
- Instant pneumatic locking system activated by an in-cab switch for ease of use and safety
- High-speed locking capability allows engagement at any vehicle speed without damage
- Steel reinforced, elastomer bonded annular seal engineered to withstand extreme temperatures and harsh environments
- Minimal moving parts for maximum reliability and reduced maintenance
- Patented timed locking mechanism ensures ultra-fast unlocking and high strength
- Provides 100% traction on demand without compromising on-road handling or driveline longevity

Construction & Design:
The ARB Air Locker is built with rugged, high-quality materials to endure the toughest off-road conditions. Its two-piece design incorporates a steel reinforced annular seal bonded with elastomer, ensuring superior resistance to extreme climatic temperatures and contaminants. The internal locking mechanism is pneumatically operated, eliminating complex mechanical linkages and reducing potential failure points. This robust construction guarantees long-lasting performance and reliability, even under heavy-duty use.
Installation & Fitment:
This Air Locker is designed to directly replace the factory differential in Dana 70/80 axles with 32 splines, making it a perfect fit for Dodge Ram 2500 and Ram 3500 trucks from 1994 to 2002. Installation requires an air compressor system (sold separately) to operate the pneumatic locking mechanism. The kit includes all necessary hardware and components for a straightforward installation, allowing drivers to upgrade their vehicle’s traction capabilities without extensive modifications.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
