AIR LOCKERS IN COMPETITION
 

 
 
   
ARB 4WD equipment
is used in extreme
off road competition
the world over. Our
commitment to research,
development, design
and production means
ARB 4x4 accessories
set the benchmark for
quality and reliability
- two things crucial to
competition use. So if
you need traction you
can rely on, rely on ARB
Air Lockers... the world's
best already do.
 

Of the many ARB products seen in off road competition, it's the one you can't see that makes the difference - ARB Air Locker diff locks continue to dominate the world's toughest off road events.

As Paul Vanderhorst, manager of Australia's world renowned Outback Challenge, states: "Our event attracts some of the world's best off roaders, competing in incredibly well prepared 4WDs. We've seen a plethora of accessories over the years, with participants constantly striving to improve their vehicle's performance. Throughout the event's seven year history though, Air Lockers are by far the preferred traction aid... 57 vehicles competed in the 2005 Challenge for instance, 48 had Air Lockers. The top 10 place getters all had front and rear Air Lockers fitted.

PERFORMANCE MODEL LINE

ARB Air Lockers are available for the vast majority of 4x4 vehicles from
around the world. In addition, a number of high performance models
are available for specialist applications such as drag racing, competition
rock crawling and heavy tank-track type snow equipment.

Designing locking differentials for applications such as these presented
our engineering team with some significant challenges. Not only must
the locker be able to withstand more traction torque than a standard
differential, but it must also tolerate massive amounts of torque
handling facilitated by the substitution of custom made high alloy
aftermarket axle shafts, which are cut with larger than standard
diameter splines. This is particularly difficult owing to size constraints
dictated by the original axle assembly. ARB met this challenge using a
combination of aerospace grade materials, and a design guided by the
results of high torque testing using computer simulations and
destructive testing.
 
 






2005 USA 'DirtSport Driver of the Year'
Shannon Campbell believes Air Lockers
are one of the keys to his success.
The 2 time winner of the world's premier
rock crawling event, the UROC, states
that "anybody not using ARB Air Lockers
is just spinning their wheels."
