Are these two hubs the same part?

Yes. Both are Southwest Wheel 5 on 4.5" idler hubs with L44649 bearings, 1/2"-20 studs and a 2,000 lb rating. The difference is how much each listing spells out, not the hardware.

Will either fit my Dexter 2,000 lb axle?

Both list Dexter compatibility. The second listing names Dexter part numbers 008-258-05 and 008-259-05, so match those against your old hub. Confirm your bearing numbers are L44649 before ordering.

Can I use these on a boat trailer?

The first listing says the hub will not work on marine trailer axles. The second does not state marine use. For a boat trailer, look for a hub rated for marine service.

Do I need to pack the bearings myself?

No. Both come pre-greased, and the first listing says the seals are already installed. Check the grease after the first few hundred miles and repack on your normal schedule.

Which one includes lug nuts?

Both include five lug nuts and a grease cap. The first kit also lists two cotter pins, two dust caps and a bolt circle guide.

Is either hub under warranty?

Neither listing states a written warranty. Keep your receipt and inspect the hub and bearings when the kit arrives.

Neither listing includes a price, so there is no price gap to weigh. Buy whichever listing matches your bearing numbers and bolt circle at checkout; the parts are interchangeable.
