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

    Definitely by again.
    By  Thor,  a  Verified Buyer  from  Southport, NC  on  June 17, 2018
    I had a horrible chattering in the rear end of my F150 every time I turned and accelerated. I put Amsoil slip lock in the rear diff, it took me about 2 minuets to do it and I noticed an immediate reduction in chatter. Within the first 50 miles of driving the chatter was completely gone and I have not heard it since. Excellent product and I would definitely recommend it. Probably saved me from eventually having to replace the rear end.
    Bottom Line
    Yes, I would recommend this to a friend.
