difference between timken rear axle bearings

i'm doing a disc conversion in my 8.25 rear end and i'm planning on doing the wheel bearings while everything is apart. however I have a question about the bearing options. there seems to be two different timken bearings spec'd for the 8.25 rear end:

timken part #6408 which looks like your usual bearing
and then this one
timken part #TRP1559TV which has this footnote
"Notes: Optional: axle repair package bearing axle repair bearing allows bearing & seal to ride on un-worn axle path"

just wondering what the difference is and what people would recommend.
cheers!

edit: found a picture of the 2nd bearing, it looks like some sort of all in one bearing?

One is a regular bearing, and the other is an offset bearing to compensate for axle shaft damage. Unless your axle shaft is damaged at the bearing surface, use the standard bearing.


From Timken:
Repair package bearings replace the original
bearing and seal on axles, which are still in
good condition, whose original bearing and/or
seal contact paths are not suitable for continued
use. The extra-wide Repair Package Bearing repositions
the rollers and seal to ride on unworn
portions of the axle closer to the flange.
