Going by the product link you provided, and assuming the pic in the ad is of the exact bearings supplied in the kit, then the kit you have bought has tapered needle roller bearings the same as what are currently on your axles.
The difference is the new bearings I believe have the outer race stuck on with a soluble adhesive to keep the bearing together during assembly to your axles and housing whereas when you pull the axles out the outer bearing race stays in the housing and has to be removed separately.
