This is the best additive on the market. Iโve been building posi differentials for 40 years and the AC Delco has never failed to reduce chatter and noise.

Just did not pour or smell like the stuff I am used to using.This along with Valvoline gear old caused the clutch packs in the 69 Chevelle Posi unit to lock up in low speed turns.Car was shaking trying to turn off a stop sign, crunching, lurching, like tossed a couple teeth in my spider gears.I drained the fluid back out, it was nasty after 2 hour drive, and refilled with different brand of each and my troubles were gone. Not sure if the additive or the lube was the issue, just glad it was not the rear end I just installed.

Within 2 normal days of driving the noise the rear differential was making totally stopped. Great product

My positrac would clunk like crazy on turns. I thought it was broken or something, but as a last resort I drained the fluid and added 2 bottles of this additive and Oh baby! She turns like butter now. Positracs need this additive.

I rebuilt my differential on my 1977 corvette and didn’t know to add this additive. The worst grinding noises ensued until I drained it, added new fluid and this additive. Problem solved.
