Description

To meet the voracious demands of the diesel dragsters, sled pullers and four-wheelers alike, ARB is proud to include this impressively strong new model in their
Performance Air Locker Series. Designed for the 2000-06 GM 2500/3500 models and the 2003 and newer
2500/3500 Dodge Ram, this new 52 pound behemoth is the first of a new breed of heavy torque handling Air
Locking differentials.

ARB's patented 2-piece case design is manufactured from heavy cross sectioned nodular iron castings for
virtually unbreakable strength and has been designed so that the side gears can be optionally upgraded to 35,
37 and 40 spline shafts. These higher splined side gears will be available in spring 2010.
As with all of ARB's Performance Lockers, the RD139 features ARB's patented Timed Gear Technology, which
offers the highest locking strength while maintaining split-second unlocking ability. The steel reinforced, bonded
seal has been designed to handle the most extreme climactic temperatures on earth complementing the
competition bred strength of the locker.

The RD139 is a huge locker that can handle huge power. How much power? Our computer modeling
suggests that this locker will handle upwards of 5 times more torque than the OE differential. We had to
increase the torque load for two reasons - first, to handle the extreme load generated by the extra traction
achieved when this differential is locked, and second, so that ARB could offer future swap-in axle
upgrades to higher torque shafts.


We can honestly say that the RD139 will not be the weak link in your drive train.

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.

AIR SUPPLY

At the flick of a dash-mounted switch, compressed air is delivered to the seal housing assembly via a nylon air line.

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.

CLUTCH GEAR

ARB's patented locking system actually supports the side gear teeth, giving you more torque handling capability, exactly when you need it.

BONDED SEAL

Steel reinforced, elastomer-bonded annular seal has been proven to handle 20,000+ cycles under the most extreme climatic temperatures on earth.

TWO-PIECE DESIGN

Machining a case from two-pieces instead of three results in a much higher dimensional accuracy of the finished assembly and has allowed ARB Engineers to improve the design of other elements, resulting in a reduction of moving parts, increased strength and a more responsive activation.

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

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.

SPIDER BLOCK

A billet-machined, alloy steel spider block supports the cross shafts, using the torque applied at each shaft to support the next shaft along.

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.

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.

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.
