Hp Axle bearings and seals

[MarauderMark]

I just noticed i have rear gear oil on the inside of my rim on the drivers side (Needs seal) so since i am going to take it in to have them changed i was wondering what the part number was for the bearings as i may go to a bearing supply house and see if they can cross reference them to some type of high performance bearing or a double with bearing or sometype of bearing that may handle the more stress it will be getting.I tried to do a search on this here but it seems no has done this..i did notice Sarges response to a Kit that Ford racing has (FRP#M-4210-C) But don't know if it's stock or and upgrade..Any info will be greatly appreciated..

Check out the following links... also note; if info comes from "Sarge" it is worthwhile!
