Friction Modifier Positraction Additive for Limited Slip Differentials

Use it for my 20 years old Pathfinder, works great. No friction, no problem at all, very satisfies.

This product works! Chattering is 95% gone.

I changed the differential fluid in my 2021 GMC Yukon 3 times per the GMC service bulletin and the groaning noise from the rear diff still persisted. I added the Yukon Limited slip additive and the noise disappeared immediately great product.

This stuff is magic. Have a 2021 GMC Yukon xl AT4 and rear differential started groaning on slow turns on a cold start. Had dealership flush and add new oil. The groaning diminished a little but was still there. So I drained the new oil and added Yukon Friction modifier with AC Delco modifier and 2 bottles of AC Delco synthetic rear axl oil. Did 4 figure 8s and the groaning is all gone. Sounds like brand new. This is a common problem with this vehicle. And this is the solution.

Works great

I recommended quality product

I’ve now used this in our 4th Gen Ram, Jeep TJ, and Excursion. Your lube may say it has friction modifier in it already but it’s not the correct ratio. Smells fantastic too, a little dab on your neck before you go out and all the pretty car ladies will flock to you. Results may vary on that last statement.

Yukon friction modifier is working well,no noise, gears are running smooth
