Description
Performance
driving
and
high
output
engines
puts
strain
on
the
drivetrain
and
can
sometimes
lead
to
failing
components,
such
as
broken
gears
or
input
shafts.
The
goal
of
the
OS
Giken
Close
Ratio
Gear
Kit
is
to
reinforce
the
transmission
internal
components
while
maximizing
an
engines
potential
by
providing
custom
gear
ratios
for
performance
driving.
Each
OS
Giken
gear
component
is
designed
and
created
from
high-quality
forged
materials,
and
then
undergoes
hard
shot
peening,
resulting
in
increased
strength
and
durability.
Furthermore,
the
gears
are
helical-cut,
rather
than
straight-cut,
to
maintain
a
quiet
and
smooth
operation,
accomplishing
full
comfort
for
street
driving
as
well
as
reliability
for
racing.
