Hello Dallas, thanks for reaching out. I looked on the Timken site and it looks like the L44642 bearing has a 1" ID and the corresponding race has a 1.98" OD.

The # L44643 bearing has a 1" ID and goes with the same race as the L44642. Meaning the Timken # TMK63VR will be a suitable replacement.

Are you needing hubs too? Or just the new bearings?

Hey Dallas, did the Timken replacement bearing and race set work out for your boat trailer? I'm curious to know if it was the right fit for your needs, as it could help others looking for similar replacements.
