Built for the ARB RD166 Air Locker Differential for Dana 60 Axles - Rear and Front Fitment, this ARB component delivers rugged durability, precise fitment, and trail-ready performance. Engineered for serious off-road use while maintaining everyday drivability.
The ARB RD166 Air Locker Differential is a high-performance traction solution designed for demanding off-road and on-road driving conditions. Crafted from durable steel, this differential allows instant locking at the flick of a switch, providing 100% traction on demand. Its pneumatically operated locking mechanism prevents the internal gears from rotating independently, ensuring maximum grip when needed and reverting to an open differential for smoother on-road driving. This versatility enhances vehicle control, reduces potential damage, and minimizes environmental impact by allowing safer, more controlled navigation through tough terrain.
Designed specifically for full float Dana 60 axles, the ARB RD166 fits both front and rear applications, accommodating a 1.50-inch shaft with 35 splines and a gear ratio of 4.56. Its robust construction and reliable operation make it suitable for heavy-duty trucks like Ford F-250 and F-350 Super Duty models from 2012 to 2014. When activated, the Air Locker maintains maximum traction even in challenging off-road environments, helping drivers overcome mud, snow, rocks, and uneven terrain with confidence. The easy-to-use switch and quick engagement make it an essential upgrade for off-road enthusiasts and professional fleet operators seeking enhanced vehicle capability.
This differential is finished in a sleek silver color and is engineered to meet the highest standards of durability and performance. Its compatibility with specified Ford models ensures a seamless installation, delivering dependable traction solutions that improve safety and vehicle handling. Whether tackling rugged trails or navigating challenging on-road conditions, the ARB RD166 Air Locker Differential offers reliable, on-demand traction enhancement to keep your vehicle moving forward efficiently and safely.
