    Those Washers Keep The O/e Stacked Needle Bearings In Line..

    If Your Still Using The O/e Loose Needles,yes... ,you Need Them..

    If Yours Were Replaced With The 'RIGHT WIDTH' Aftermarket Cage Type, Then Those Washers Are Unneeded And You Can Do With Out...
    HOW DOES THE CAGE FIT? GOT PICTURE'S?

    thats the standard caged bearings and I don't use washers nor does pro-x or WSM supply them even with a complete kit
