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 Tea exit or in stock at the Stan Houston’s store off of W. 12th St.

Differential Product Overview

Slip Lock

AMSOIL 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.

Stops chatter

By  BLAKE 7,  a  Verified Buyer  on  April 28, 2024
When I bought my truck the rear differential had been rebuilt. When I got it home I installed AmsOil gear lube in it. Immediately I noticed the chatter coming from the rear differential. I called the tech at amsoil and he assured me that the gear lube has the necessary qualities and an additive is not necessary. I just lived with the chatter in the rear differential. A few months ago I needed a mechanic to test drive it to see if there was something up with the transmission. He said no but you’ve got a lot of chatter in the rear differential. I said well I have amsoil in there and they said it’s not necessary to put an additive in there. He says I know, I use amsoil and everything I own. But you have to put the additive in the rear differential anyway. Two tubes he said. When I got home I ordered the differential additive slip lock. When it came in I installed it and went out and drove it around for about 15 minutes and then found an empty parking lot and did figure eights. When I drove away I did not notice any chatter, it was gone. I don’t care what anybody says if you got chatter and you still using amsoil gear lube in your rear differential but no additive, install a couple of tubes of the slip lock. It will be gone, and it will be smooth when you turn corners.

 

Slip lock is better than GM brand

from Chicago

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.

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.
