The
Wavetrac
LSD’s
ability
to
bias
under
ZERO
to
LOW
load
situations
is
what
makes
it superior
to
everything
else
on
the
market.
Wavetrac’s
manufacturing
tolerances
and
finish
requirements
meet
or
exceed
all
OEM
standards.
Wavetrac®
differentials
are
built
in
American
plants
operating
to
ISO9002
and
TS16949
standards.
Our
quality
control
system
checks
components
at
every
step
as
they
travel
through
the
manufacturing
process.
How
is
Wavetrac
Different?
To
best
understand
how
the
Wavetrac®
is
truly
different
from
the
other
gear
differentials
on
the
market,
you
first
have
to
understand
the
primary
problem
that
the
Wavetrac® solves.
The
problem: Loss
of
drive
during
zero
or
near-zero
axle-load
conditions.
Zero
axle-load
is
a
condition
that
occurs
during
normal
driving,
but
creates
the
most
noticeable
problems
when
driving
in
extreme
conditions.
Zero
or
near-zero
axle-load
is
the
condition
that
exists
when
there
is
‘no-load’
applied
through
the
drivetrain,
when
one
drive
wheel
is
nearly
or
completely
lifted
(often
in
aggressive
cornering).
It
also
occurs
during
the
transition
from
engine
driving
a
vehicle
to
engine
braking
and
back,
even
with
both
drive
wheels
firmly
on
the
ground.
Here’s
how
that
loss
of
drive
hurts
you:
1)
If
you
lift
a
wheel,
all
gear
diffs
except
Wavetrac®,
will
NOT
power
the
other
wheel.
2)
During
the
transition
from
accel
to
decel,
all
gear
diffs
except
Wavetrac®,
do
nothing.
Why
does
this
happen?
All
gear
LSDs
work
in
basically
the
same
manner:
they
divide
the
drive
torque
between
the
two
axles,
applying
drive
to
each
side,
up
to
the
available
grip
of
each
tire.
The
amount
of
drive
torque
one
wheel
can
get
over
the
other
is
described
as
the bias
ratio,
a
measure
of
the
torque
split
across
the
axle.
Standard,
open
differentials
have
a
bias
ratio
of
1:1.
They
can
only
apply
as
much
drive
torque
as
there
is
available
traction
at
one
wheel.
When
one
wheel
loses
grip,
the
total
available
drive
is
lost
as
well
(at
a
1:1
ratio).
All
your
power
goes
out
the
slipping
wheel
–
along
the
path
of
least
resistance.
Torque
biasing
differentials
offer
increased
bias
ratios
over
open
differentials.
For
example,
if
a
diff
has
a
bias
ratio
of
2.5:1,
then
it
can
apply
drive
torque
to
the
wheel
with
the
most
traction
(gripping
wheel)
at
2.5
times
the
traction
limit
of
the
wheel
with
the
least
traction
(slipping
wheel).
This
is
a
significant
improvement
over
an
open
diffs
most
of
the
time.
The
problem
is
that
when
one
tire
has LITTLE or NO grip
(zero
axle-load),
the
other
wheel
gets ZERO
DRIVE,
because
(basic
math
here):
2.5
x
0
=
0.
Lift
a
wheel
(or
substantially
unload
a
wheel)
and
you
get
zero
axle-load
on
that
side
–
that
means
that
during
the
time
the
wheel
is
unloaded,
the
typical
diff
will NOT power
the
wheel
that’s
still
on
the
ground.
No
matter
how
high
the
bias
ratio, you
get
no
power
to
the
ground.
During
the
transition
from
accel
to
decel,
where
you
have
near
zero
torque
on
the
axle,
even
if
the
wheels
are
on
the
ground,
the
typical
diff
is
unable
to
begin
applying
drive
torque
until
AFTER
the
zero
torque
condition
is
over.
While
this
condition
is
generally
short-lived,
the
fact
that
most
diffs
can
do
nothing
during
that
time
means
that
there
will
be
a
delay
once
the
zero
torque
condition
stops
–
creating
a
reaction
time
in
the
driveline.
