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

Ecause one back wheel spinning is not cool . I bought a new traction unit for my crewcab s10 because one rear wheel spinning is not cool .the unit i ordered requir3s this so the clutches will no5 chatter and act crazy- great product - traction unit works great. This stuff does stink but hey so does gear oil

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.

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

fast delivery good quality it works

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.

I recommended quality product
