Review ARB Air Locker D44 35 Spline Locking Differential New for DANA

The ARB RD157 Dana Air Locker D44 35 Spline Locking Differential is a high-performance off-road component designed for serious 4x4 enthusiasts who demand the ultimate in traction and durability. This differential is specifically engineered for use with Dana 44 axles and comes with an integrated air locker system that allows you to instantly engage or disengage the differential lock for maximum traction in challenging off-road conditions.

The ARB RD157 Differential features a robust 35 spline output shaft that is stronger than the original equipment 28 spline shaft, ensuring optimal power transfer and longevity. The differential housing is made of high-strength steel and is precision machined to ensure a perfect fit and optimal gear mesh. The differential gears are manufactured using heat-treated chrome molybdenum steel, providing superior strength and durability.

The integrated air locker system in the ARB RD157 Differential is activated by an external air compressor, which applies pressure to the locking mechanism, engaging the differential lock. This allows both the driver's and passenger's sides of the differential to turn at the same speed, providing maximum traction in low-traction situations such as steep climbs, deep ruts, or slippery surfaces. The air locker system can be engaged or disengaged on the fly, making it an invaluable tool for off-road driving.

The ARB RD157 Differential also comes with an internal bypass oil filter and breather, which help to maintain the differential's oil pressure and keep contaminants out of the gear oil. Additionally, the differential comes with a set of high-quality seals and gaskets, ensuring a leak-free installation.

Installation of the ARB RD157 Differential is relatively straightforward, with detailed instructions provided in the kit. The differential comes with all necessary hardware, including new axle nuts and studs, making it a complete solution for upgrading your Dana 44 axle with a stronger, more capable differential.

In summary, the ARB RD157 Dana Air Locker D44 35 Spline Locking Differential is a high-performance off-road component that provides maximum traction and durability for serious 4x4 enthusiasts. With its robust 35 spline output shaft, high-strength steel housing, and integrated air locker system, this differential is the ultimate solution for those who demand the best from their off-road vehicle.
