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

:)

Great product for stopping or at least slowing shakes and shimmies in the transition.

Makes slippery things slipperier

Used it with Mobil One synthetic on my 2016 Challenger and it finally quieted the beast down....

Great product

easy to use and will quiet noises from limited slip rear end

I use this and 3 quarts of Mobil1 75w90 LS gear oil in my 2002 Tundra. Without this additive, the LS clutches will chatter.

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

trans-x posi track additive have used this for years with no bad results

Good product.. the rear in my truck feels like its a little bit smoother
