    5 out of 5 Blue Diamond GL-5 80W-110

    It is getting harder to find a gear oil that does not have the limited slip or anti-slip additive already added to it.
    My 2017 ram 2500 has a AAM 11.5” rear end which contains the anti-slip gear set which requires a gear oil without the limited slip or anti-slip additive to perform properly.
    Hot shot secret blue diamond was the perfect selection for my next service.
    I replaced my stock OEM cover with a PML aluminum cover & made the switch to the 80W-110.
    The last snow and ice storm that approached us and put almost 12 inches of snow and at least an inch of ice down before put rear end & anti-slip to the test – fortunately the anti-slip worked perfect with the hot shot secret blue diamond gear oil added.
    I have no documented proof to show for the rear end running cooler or really smoother but the anti-slip perform perfect with this gear oil I highly recommend this product – if you have the AAM 11.5” Anti-Slip rearend.
