AMSOIL Slip-Lock
Differential additive

Formulated with advanced friction modifiers, AMSOIL Slip-Lock differential additive is designed to eliminate gear-housing chatter in your cars, trucks and SUV's equipped with limited-slip, positraction and locking differentials.

Formulated for use with both synthetic and petroleum gear lubricants. Safely replaces manufacturer recommended friction modifiers.

It also reduces the banging and clunking associated with automatic locking differentials.

One four-ounce bottle treats differential capacities of two to four quarts. Not for use in automatic transmissions or other applications requiring ATF.

Here is a detailed reason on what causes gear housing chatter.

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 Lubes, this product is an excellent solution to to the problem.
