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

    You cant beat Amsoil products! Been using Amsoil for over 30 years Will never use anything else, so when I needed a limited slip additive I put this in both my Mustangs along with Amsoil severe duty gear oil. Not a sound coming from the differential. Forget all other brands, TRUST Amsoil!
    Bottom Line
    Yes, I would recommend this to a friend.

    By  JC,  a  Verified Buyer  from  TX  on  September 16, 2020
    A required additive in some cars, my C3 requires it so I added it in after replacing with Amsoil gear oil 75-90, it was grinding upon turning to the left, the grinding stopped after this added lubricant.
    Bottom Line
    Yes, I would recommend this to a friend.
