Yukon Friction Modifier Additive for Limited Slip/Posi - 4 Ounce Bottle

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.

fast delivery good quality it works

Works great

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.

I recommended quality product
