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

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

A tube of this and fresh Mobil 1 diff fluid fixed my horrendous LSD chatter problem. Based on internet posts was originally looking for Ford friction modifier but have always had good luck with CRC products. Did not disappoint. Drives like a new car, doesnt fight me in turns anymore yet still locks up tight when really hit it. Replaced Royal Purple synthetic that said it had the modifier, but guess it wasnt enough.

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

works well, no chatter .

great price I assume it works like the factory stuff.

Diff sounds good

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

worked good! Half a bottle for a 2020 scat pack differential No chatters with sharp / wide turns clutches grab normal I’ll buy it again . Not much else to say.

As described. Does the job!!!

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