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

If your Porsche Cayenne transfer case starting to have chattering/locking up issue during cold or morning start when you turn the wheel sharp OR you noticed your rear tires wearing out way faster than the fronts, add a tube of this additive to the transfer case during the transfer case oil change. This solves the issue !

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.

Makes slippery things slipperier

I bought this for a 2020 Ram 1500 classic. The additive seems to work but my rear end still makes an ever so slight noise upon sharp turns when accelerating, and when its cold. Now when I say it makes a noise you have to really listen for it and it only last 1 or 2seconds then its over with. And from what I have read this is a normal occurance for this type limited slip rear end. I dont remember it making the noise before the oil change, but I wasnt listening for it either, and after the oil change I was listening for it. So Im going to say its fine. The noise hasnt got any worse, and doesnt do it regularly.

The bottle of magic got rid of the AWFUL chatter in the LSD of my Toyota Tacoma TRD Sport.

Works great. Took the chatter away from the clutch pack.

Stopped my rearend chatter.
