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. ;

VERIFY FITMENT
Differentials are not one size fits all; there may be differences for the same application. Be sure to verify fitment before ordering.
Features
BONDED SEAL
Steel reinforced, elastomer-bonded annular seal has been proven to handle 20,000+ cycles under the most extreme climatic temperatures on earth.
FLANGE CAP ASSEMBLY
A billet-machined, alloy steel spider block supports the cross shafts, using the torque applied at each shaft to support the next shaft along.
AIR SUPPLY
At the flick of a dash-mounted switch, compressed air is delivered to the seal housing assembly via a nylon air line.
CLUTCH GEAR
ARB's patented locking system actually supports the side gear teeth, giving you more torque handling capability, exactly when you need it.
TWO-PIECE DESIGN
At the flick of a dash-mounted switch, compressed air is delivered to the seal housing assembly via a nylon air line.
SPLINED SIDE GEAR
High-grade surface treatments, forged nickel alloy steel and ARB's patented timed locking system make this the most ‘lockable’ gear in the industry.
WAVE SPRING
WAVE SPRING
Instead of a complex external actuator system to engage/disengage the lock, ARB Air Lockers® use up to 12 return springs to support the entire profile of the locking gear for a fast, positive and independent disengagement.
PINION GEAR
Combining the strength of forged nickel alloy steel with redefined gear-tooth geometry, ARB has revolutionized locking differential gear design to yield structural advantages of up to 30% over commercially available high strength gears.
SPIDER BLOCK
Steel reinforced, elastomer-bonded annular seal has been proven to handle 20,000+ cycles under the most extreme climatic temperatures on earth.
LONG CROSS SHAFT
Alloy steels and performance surface technology make for a high-pressure running fit that can handle an enormous amount of punishment.
DIFF CASE
Fully machined, one-piece nodular iron diff carrier case offers the rigidy of a one-piece factory differential with twice the standard number of pinion gears to cope with the torque.
CROSS SHAFT RETAINING PIN
Custom made, one-piece hardened retaining pins lock into the assembly using a tapered thread junction.
FORGED GEARS
With phenomenal forces being applied to the side and pinion gears within the differential, ARB has invested heavily in the application of forged gears, typically found in heavy-duty commercial, race and agricultural transmissions.
TRUSTED TRACTION
A relentless commitment to research and design, the use of quality materials, and an uncompromising approach to manufacturing have all contributed to the Air Locker’s® success in over 100 countries worldwide. Designed and manufactured in Australia, you can trust ARB Air Lockers® for traction in just about any terrain - rock, clay, gravel, sand, snow or mud.
WINNER'S CIRCLE
ARB Air Lockers® continue to dominate the world’s toughest off-road events, namely Ultra4's King of the Hammers. Used by some of the biggest names in off-road competition, Air Lockers® are just as at home plugging through mud or scaling near-vertical rock ledges as they are on your local trail. Competition drivers stake their reputations on quality and reliability. If they can trust Air Lockers® to get them across the finish line, then you can be sure they’ll survive anything you throw at them off-road.
