Product Overview

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

    Great stuff
    By  LYLE,  a  Verified Buyer  from  Arizona   on  November 02, 2023
    I add this to the 75w-140 gear oil that goes into the 2014 Ram1500 every 50,000 mile service. Also use it in the Jeep JKU along with Amsoil 75w90. Despite Amsoil saying their gear oil already has a posi additive. Doesn’t hurt to play it safe, as Mopar calls out for the use of a posi additive.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  JACK,  a  Verified Buyer  from  Show Low AZ  on  December 08, 2022
    Years ago I bought a 1991 Nissan Pathfinder 4x4 and changed the rear differential fluid. I had metal noise chatter. Found out I needed a slip lock fluid Added Amsoil and within 1 day of driving around town a couple of times, problem fixed. I change the rear differential fluid every 50k miles and always add the Amsoil Slip Lock.
    Bottom Line
    Yes, I would recommend this to a friend.
