Hey David, thanks for reaching out!
It sounds like you have drums for a 3,500 lb axle so in that case, yes, the Timbren Axle-Less Trailer Suspension # ASR3500S05 will work for your application.
To verify this on your end, your hub needs to use the following bearings and have these grease seal dimensions:
- Inner Bearing: L68149
- Outer Bearing: L44649
- Grease Seal: ID 1.719" and OD 2.565"
If you have something else please let me know and I'll be happy to help you find what you need!
