3,500# trailer hubs 5X4.5
 

These came on a trailer I bought new and replaced with brakes. They have about 4,000 miles on them.They are 5 bolt on 4 1/2" pattern. Bearings are standard size for many axles, but they came off a Dexter for reference. Studs are 1/2". They sell for $56 each on etrailer.
$40 for the pair. I can ship via Pirateship for cost or bring them to MCACN for free.
