Effectively Eliminates Gear Housing Chatter
Product Code: ADA
ORMULATED WITH ADVANCED FRICTION MODIFIER. Designed to eliminate gear-housing chatter in cars, trucks and SUVs equipped with limited-slip, posi-traction and locking differentials. Formulated for use with both synthetic and petroleum gear lubricants and safely replaces manufacturer-recommended friction modifiers.
When making a turn, the outer wheels of a vehicle must travel faster than
the inner wheels. It is up to the differential to act as a balance
arm, establishing constant equilibrium of torques and forces between
the left-hand and right-hand driven wheels. In standard (or open)
differentials, power is directed to the wheel offering the least resistance.
This works well when making a turn, but in a situation where one wheel
is lifted off the ground, it causes the suspended wheel to turn while
the other remains motionless.
Limited-slip (or positraction) and locking differentials
are traction-increasing devices. Locking differentials transfer all
available torque to both wheels. The teeth of the spider assembly
engage with those on the locker clutch, causing both axle shafts to
operate as one. Locking differentials don't allow one drive wheel
to spin while the other remains stationary. Instead, they keep both
wheels in drive mode, but unlock to permit different wheel speeds
when turning. The engaging and disengaging of the teeth on automatic
locking differentials often causes a banging and clunking sound. Manual
locking differentials usually use an electric motor or vacuum diaphragm
to engage the locker, reducing this noise.
differentials allow different wheel speeds when turning, but when
one wheel loses traction, greater torque is transferred to the wheel
offering more resistance. Limited-slip differentials make use of friction
between clutch plates, as opposed to the meshing teeth employed by
locking differentials. Transferring less torque per side, limited-slip
differentials are generally smoother and quieter than locking differentials,
but still sometimes "chatter" when transferring torque to
the wheel with traction.
In some differential applications, a friction modifier
additive is necessary to reduce chatter. AMSOIL Slip-Lock Differential
Additive is formulated with advanced friction modifiers and is designed
to eliminate gear-housing chatter in cars, trucks and SUVs equipped
with limited-slip, positraction and locking differentials. It also
reduces the banging and clunking associated with automatic locking
AMSOIL Slip-Lock Differential Additive is formulated
for use with both synthetic and petroleum gear lubricants and safely
replaces manufacturer recommended friction modifiers. Its convenient
flip-top dispenser provides quick and easy application to the gear
housing. One four-ounce bottle of Slip-Lock treats differential capacities
of two to four quarts. It is not for use in automatic transmissions
or other applications requiring ATF.
NOTE: AMSOIL Synthetic Gear Lubes do not require
the use of this additive. However, not all differentials respond the
same and if chatter is noticed, the addition of AMSOIL Slip-Lock will
eliminate it. For chattering differentials not running AMSOIL Gear
Lube, this product is an excellent solution to the problem.
