Slip Lock Gear Oil Additive

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.

Bottom Line
Yes, I would recommend this to a friend
