Thanks for that information, and from your specs you have 3,500 lb axles, and we do have the hub and drum you need, as well as the electric brakes that will fit. The only thing you didn't mention was your hub's wheel bolt pattern, which will be either 5 on 4-1/2" or 6 on 5-1/2".

If you aren't sure what yours is I have added a link to a help article which tells you how you can determine it. Once you know that, you will need one of the following hub and drums (depending on your bolt pattern):

- 5 on 4-1/2" Bolt Pattern: Dexter Trailer Hub and Drum Assembly for 3,500-lb Axles # 84546UC3

- 6 on 5-1/2" Bolt Pattern: Dexter Trailer Hub and Drum Assembly for 3,500-lb Axles # 84656UC3

For grease I recommend the LubriMatic Disc/Drum Brake and Wheel Bearing Grease # L11382; for a bearing packer I recommend the Bearing Packer # PTW1218 or # ALL647646.

Then for electric brakes that will work with your 4-bolt mounting flange you can choose from manual-adjusting or self-adjusting brakes, though I do recommend the self-adjusting to make things easier.

- Self-Adjusting Brakes: Electric Trailer Brake Kit # AKEBRK-35-SA

- Manual-Adjusting Brakes: Electric Trailer Brake Kit # AKEBRK-35

The manual adjusting brakes will need Brake Adjustment Spoon # W80630, and for both brakes you will need the Mounting Hardware for 10" Brake Assemblies # BRKH10B.

I have added links to video reviews for you to check out as well.
