ARB RD99CE Air Locker Differential

Engineered and manufactured in Australia, the RD99CE competition Air Locker has been designed around the requirements of top-flight ULTRA4 racing. Each technical advancement addresses a specific concern from teams competing in the worlds toughest 4x4 events and is a direct result of testing within these same races. This Air Locker is for the top-tier racer or the hardcore enthusiast who demands the best equipment for their vehicles. Everyone can benefit from the research and development ARB has committed to the competitive racing circuits. Among the many new design features is an integrated ring gear bolt locking system engineered to prevent the backing out of Ford 9 in. Trac-Loc bolts. Fully reusable and able to resist the high torque loads applied to bolt removal, the locking tabs are designed for disassembly and reassembly for fast pit work on ring gear swaps compared to all other bolt locking systems. Key to the design is the ability to oppose the adverse effects of axle shaft eccentricity caused by typical steering joints,thereby overcoming a common problem with front applications where the differential is offset too far toward one wheel. Achieving new levels of load, wear and impact resistance, the RD99CE case is 290 percent stronger overall compared to standard lockers. Designed with deeper locking engagement, the RD99CE ensures locking functionality is retained even after sustaining significant clutch gear tooth damage from locking under throttle.
