The Trailer Hub part # AKIHUB-440-2-1K that you referenced is designed to fit a BT8 spindle like the part # TRU94FR which has an overall length of 8-1/4 inches and a stub length of 3-3/8 inches. That means the remaining section where the seal, bearings, castle nut and washer ride is approximately 4-7/8 inches.
