Hey Richard, the correct bearing kit you want is the part # BK3-210 based on the info you gave me. You listed all of the correct info so that makes it really easy to pick out! Sometimes 7k axles use different seals but you gave that info so I know which seal you need. Are you wanting to keep a spare set on hand or did yours go out?
