ARB Air Locker Differential 31 Spline 9.25in Rear ZF C-Clip Axle: Ram 1500 (2011-24)

ARB Air Locker Differential

2011–2024 Ram 1500

RD269

Overview:

The ARB Air Locker Differential is the ultimate traction solution designed specifically for the 2011–2024 Ram 1500 equipped with the 31 spline 9.25-inch rear ZF C-Clip axle. This advanced locking differential provides instant, on-demand traction by pneumatically locking the axle shafts together, ensuring both wheels turn in unison. Ideal for off-road enthusiasts and drivers who demand superior control in challenging terrain, the Air Locker enhances vehicle capability without compromising on-road drivability.

With a simple switch inside the cab, the Air Locker engages instantly, allowing you to maintain momentum through mud, snow, rocks, and uneven surfaces. When disengaged, it functions as a conventional open differential, preserving smooth handling and tire wear during normal driving conditions.

Key Features:

The ARB Air Locker Differential combines innovative technology with robust engineering to deliver reliable traction performance:

• Instant pneumatic locking system activated via a dashboard switch for ease of use
• Allows activation at any speed, providing traction when you need it most
• Prevents axle shafts from turning independently, maximizing traction on all surfaces
• Steel reinforced, elastomer bonded annular seal designed to withstand extreme temperatures
• Two-piece design with minimal moving parts for enhanced durability and reliability
• Does not affect on-road drivability or cause additional driveline wear
• Patented locking mechanism ensures high strength and ultra-fast unlocking
• Compatible with the 31 spline 9.25-inch rear ZF C-Clip axle found in Ram 1500 models from 2011 to 2024

Construction & Design:

The ARB Air Locker is engineered with a two-piece design that balances strength and simplicity. Its steel reinforced, elastomer bonded annular seal is built to endure the harshest climates, from extreme heat to freezing cold, ensuring reliable operation in all environments. The minimal moving parts reduce wear and potential failure points, resulting in a robust and long-lasting differential upgrade.

Designed to integrate seamlessly with the factory axle housing, the Air Locker maintains the structural integrity of your Ram 1500’s rear differential while delivering superior traction performance.

Installation & Fitment:

This Air Locker is a direct fit for the 2011–2018 and 2019–2024 Ram 1500 models equipped with the 31 spline 9.25-inch rear ZF C-Clip axle. Installation requires removal of the factory differential carrier and replacement with the ARB Air Locker unit. While professional installation is recommended to ensure proper setup and air line routing, the kit includes all necessary components for a complete installation.

An air compressor is required to operate the Air Locker system; this is sold separately and must be installed to provide the pneumatic pressure needed for activation.

What's Included:

• ARB Air Locker differential unit
• Activation switch for in-cab control
• Solenoid valve for pneumatic operation
• Airline and bulkhead fitting for air supply connection

Ideal For:

The ARB Air Locker Differential is perfect for Ram 1500 owners who frequently encounter off-road conditions such as mud, snow, rocks, and uneven terrain. It is especially suited for enthusiasts who require reliable traction without sacrificing everyday drivability. Whether you’re trail riding, overlanding, or navigating slippery surfaces, this Air Locker provides confidence and control to keep you moving forward.
