Slip Lock Gear Oil Additive

Differential Additive

AMSOIL Slip Lock® Differential Additive (ADA) is formulated with advanced friction modifiers and is designed to eliminate gear-housing chatter in cars, trucks and SUVs equipped with clutch-type limited-slip differentials.

Excellent price!

AMSOIL’s full retail is less than the Mopar OEM product. That’s why we made it so that shops can buy a better product for less. Of course it’s available to anyone here out of our Omaha store.

Product Overview

AMSOIL's Slip Lock Gear Oil AdditiveAMSOIL Slip Lock Gear 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.

Note: Our differential oils have this installed already but generally 15% of the differentials out there will still need additional. This product can easily be added of chatter is noticed. It’s also great for any GL5 gear lube, OEM or name brand which doesn’t have the appropriate amount.

Customer Comments:

Excellent product I use every differential fluid change.

I own a Ford which is notorious for gear chatter when I change the front and rear differential fluid without adding slip lock. Amsoil sells it in the exact size I need, so there’s no leftovers to worry about losing or misplacing. I just add it in with my differential fluid.


Slip lock is better than GM brand

Installed a new ring and pinion with Yukon brand limited slip differential on a 8.2″ 10 bolt. Works great with one tube of AMSOIL Sliplock and 75/140 gear lube.

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.
