Product Description

The ARB RD116 Air Locker Differential is engineered to enhance the off-road capability of vehicles equipped with Dana 44 axles. Designed for axles with 30-spline shafts and gear ratios of 3.92:1 and higher, this air locker provides 100% traction on demand, allowing you to tackle challenging terrains with confidence.

When engaged via a dash-mounted switch, the RD116 uses compressed air to lock the differential, ensuring both wheels turn in unison for maximum traction. Its robust two-piece design minimizes moving parts, enhancing reliability and longevity. The patented 'timed' locking mechanism ensures rapid engagement and disengagement, while the steel-reinforced, elastomer-bonded annular seal withstands extreme temperatures and conditions.

Compatible with ARB's air compressor systems (sold separately), the RD116 is a must-have upgrade for off-road enthusiasts seeking improved performance without compromising on-road drivability. Whether navigating rocky trails or slippery slopes, the ARB RD116 Air Locker delivers the traction you need when you need it most.
