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

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

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

Installed new gears which I purchased here and since my 67 GTO has Safe-T-Track, it requires this additive. Works as it should, just pour the complete contents into the rear end prior to filling with fluid. This helps it mix itself when you add the diff. fluid (which I also purchased here).

Easy to get into rear diff with the package design

:)

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

As described. Does the job!!!
