Slip Lock



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 squeeze-tube packaging provides quick and easy application to the gear housing. One four-ounce tube of Slip Lock treats differential capacities of two to four quarts. It is not for use in automatic transmissions or other applications requiring automatic transmission fluid.

NOTE: AMSOIL synthetic gear lubes do not require this additive. However, not all differentials respond the same and the addition of AMSOIL Slip Lock will eliminate chatter in mechanically sound differentials.

  • Contains advanced friction modifiers
  • Helps eliminate gear housing chatter
  • Recommended for cars, trucks and SUVs
