Expert Reply:
It sure is Randy! The Trailer Idler Hub Assembly for 2K Axles item # AKIHUB-545-2-LF-1K is indeed a comparable alternative or replacement for the Dexter item # 8-258BTUC1.
Both are designed for 2,000-lb trailer axles with BT8 spindles and come with new lug nuts and a grease cap.
The Idler Hub Assembly item # AKIHUB-545-2-LF-1K has a 5 on 4-1/2 lug nut pattern and comes pregreased with bearings and seals already packed. You'll be able to pull it out of the box and put it on your trailer's spindle.
What kind of trailer do you have and what do you use it for? Feel free to answer this and throw in any other questions you have, where it says Add Comment.

I have a 2016 Pleasant Valley Tag teardrop camper. Thank you very much for the information. I have ordered the hubs and have an E-trailer installer ( Dave's Automotive in Valparaiso Indiana ) scheduled to install on Thursday. Everyone has been very helpful and any trailer needs in the future will be with Etrailer.
