    limited slip additive

    Starting to get some shatter in my limited slip rear end on 1979 Pontiac. Changed out gear oil with fresh and added this additive. Rear end operation on car now is back to smooth.

    posie rear end

    This is a must have for Corvette rear ends. My c3 sounded like it was going to fall out. Drained all I could and added the additive and filled with clean gear lube, did the figure 8's , like a new car, no more noise and jumping. Don't leave home without it.

    Works as intended

    Changed the differential fluid on my 2006 Cadillac XLR. Added this additive. Seems to be quieter going down the highway.

    Looks easy to install with the tip. A hose should fit and empty contents into differential.

    Great OEM additive.

    Vintage Restoration

    Great for completing vintage restorations and for use on vehicles that were never designed for Synthetic Oils
