Would you be able to clarify specifically what you are referencing in terms of depth from the edges of Dexter Trailer Idler Hub Assembly # 8-258-50UC1? Do you mean the depth of the inside of the hub bore, the total length (depth of the hub bore) or a different measurement? If you can email me with a bit more specific I'd be happy to try and find what you need.

I went out to the warehouse to measure the length of the hub bore of Dexter Trailer Idler Hub Assembly # 8-258-50UC1 and found it was 4", as you can see in the accompanying photo.

@HubO Jason, from what I can find, all of the hubs we have are going to be at the 4" or larger mark, unfortunately. From what I understand those were typically found on older trailers and are no longer made so you're going to need to either swap your axle or your spindles.
