1985 FLHT primary bearing upgrade.

[janne63]

I have 1985 FLHT belt drive with tappered mainshaft.Does this Zippers bearing fit ? http://www.zippersperformance.com/catalogue/showproduct.asp?cat=822&prod=1889
Or this Jimms bearing http://www.toledohd.com/eshopprod_cat_7083-27060_product_1145163.JIMS_PRIMARY_BEARING_UPGRADE.htm

I have pulled tons of primary over the years and never seen these bearings walk on the mainshaft ,the added bonus to the stock bearing is the seal rides on race so replacing race give a new seal surface if this seal scores the main shaft you would have to replace it instead of race ,I would stay stock
