Question:
What information on a trailer do y’all need for rotors and hub assembly.

Hello Rickey, thanks for reaching out. The axle weight capacity, hub bolt pattern, and bearing/seal sizes would be what we would need to get you the right hubs and rotors.
There should be a sticker on the axle tube that shows the weight capacity.
If you can pull a hub and unpack the bearings there should be a number stamped on each bearing, or you can measure the ID with a micrometer.
If you can leave a reply below with all that info, I am happy to look into it and get back to you with some part numbers.
