K&W 402508 Trans-X Posi Trac Limited Slip Gear Oil Additive - 7 Fl Oz

Great additive for my 02 Explorer w/ limited slip differential. Keeps the clutches from chattering.

Good stuff! Here is how i used it: How to change the differential fluid in a 2012 Dodge Challenger 3.6 liter. Link: https://www.youtube.com/watch?v=3HJ6zoGZy5k

This trans-x limited slip additive works very, very well in place of factory additives/modifiers. I had put this fluid in my 04 Chevy Express 3500 with the big ole 14 bolt rear end, and all the chattering that was going on was taken care of after throwing this stuff in during a fluid change. Its very well priced and seems to work just as well as comparable OEM fluids.

I picked this up in a pinch for my 2008 Ford Mustang GT when I was changing our the rear end gears. I couldnt get my hands on the Ford friction modifier, so I picked up a tube of this instead. I was a little skeptical because I knew nothing about it. However, is been two weeks since I put this in my differential, and everything has been just fine. I dont get any chatter from the limited slip differential. Everything feels normal with the car. I would use this again.

Many vehicles need this, check if your project requires it. I use it when necessary and it is a great additive.

Great product

great price I assume it works like the factory stuff.

Followed the directions and no issues here with my 2006 Toyota Tundra

Works great for my Detroit Locker

Stopped my rearend chatter.
