Frequently Asked Locker Questions
WHAT ARE EXTREME TRACTION DIFFERENTIALS?
Extreme Traction is a trademark of Powertrax that describes
its family of advanced traction-adding differential products. All Powertrax differentials
are designed to deliver maximum power and optimum performance in extremely demanding
vehicle applications.
WHY ARE CONVENTIONAL DIFFERENTIALS INADEQUATE?
Most vehicles are equipped with "open" differentials
that have not traction enhancement capabilities. Although these differentials provide
the required wheel "differentiation" for turning, they actually deliver
all engine power to the slipping wheel in poor traction conditions. This design characteristic
makes open-differentials inadequate in many driving situations. Both on-road and
off, vehicles frequently need more traction than open-differentials provide, to prevent
slipping, sliding, or getting stuck. Numerous designs, such as limited-slip/posi
differentials, attempt to overcome open-differential shortcomings with varying degrees
of success.
WHY DO LIMITED-SLIP/POSI DIFFERENTIALS FALL SHORT?
As the name implies, limited-slip/posi differentials limit
or reduce wheel slippage, but do not eliminate it. By applying friction with clutches
or cones to the side gears inside the differential, unwanted wheel slippage is reduced.
The degree of reduced wheel slippage is determined by the amount of friction, or
"breakaway torque," applied to the side gears. While performance varies
from one design to another, as little as 15% to 25% of engine torque will be delivered
to the higher traction wheel when new and will decline with use. Although better
than open differentials, limited-slip/posi differentials do not provide the maximum
traction capabilities of locking differentials.
WHAT IS A LOCKING DIFFERENTIAL?
Unlike limited-slip/posi differentials, locking differentials
deliver 100% of engine torque to both wheels, even if one has zero traction. Locking
differentials, commonly referred to as "lockers," are available in either
manual or automatic configurations: Manual lockers operate like open differentials
when deactivated. When manually activated, they deliver maximum traction by essentially
joining together both wheels. Because manual lockers do not differentiate when activated,
care must be used to insure they are manually disengaged when making turns on hard
surfaces to avoid potential damage.
Automatic lockers deliver maximum traction without requiring manual activation and
deactivation. The wheels are mechanically "locked" together when the vehicle
is traveling straight ahead. As the vehicle begins to turn, it automatically; unlocks
to allow required wheel differentiation throughout the turn, and then automatically
re-locks. Although not as smooth and as quiet as limited-slip/posi differentials,
vehicles equipped with automatic locking differentials provide differentiation and
the highest level of traction output.
WHY IS THE POWERTRAX NO-SLIP DIFFERENTIAL "THE ULTIMATE
DIFF?"
With a Powertrax No-Slip Differential, there is no need to
compromise. The product delivers full differentiation with the maximum traction of
an automatic locking differential, plus combines the smooth and quiet operation of
a limited-slip/posi differential. Power is automatically directed to provide full
engine torque to both wheels, even if one has zero traction. Unwanted wheel slip
is controlled to provide the best traction output. Transitions are smooth and quiet,
from equal torque distribution to both wheels, to differential action when making
a turn. This combination of unique characteristics allows the broadest range of applications.
Model are available for virtually any type vehicle, including late model 4x2 and
4x4 trucks, sport utility vehicles, vans, recreational vehicles and many rear wheel
drive passenger cars.
HOW EASY ARE POWERTRAX DIFFERENTIALS TO INSTALL?
Powertrax No-Slip Lockers have been specially designed for
ease of installation. Because they can be installed inside the existing differential
case, the highly accurate factory ring and pinion setup does not need to be adjusted,
and in many cases doesn't even have to be touched. Complete easy-to follow, model-specific,
step-by-step instructions are supplied with each unit. No special tools are required,
and most installations can be completed in a couple of hours.
Powertrax No-Slip Differentials are also available in special high strength cases.
Only these case versions need the ring and pinion to be reset, requiring proper or
professional installation,
