I have a set of new bearings and seals that someone gave me for a 13' Casita
I used to own. That trailer had a 2200/2500 lb torque flex axle
by Dexter. It's a Redline BK1-150 part #. Bearing# L44649. If I trim the packaging, both will fit in a small flat rate box. They are free for the cost of shipping.
