Question:
I have a 2004 2 axle Extreme boat trailer and I need 4 enclosed wheel hubs with bearings and brakes complete as a one part hub replacement, if possible. I also need the tongue master cylinder slide, which is a Model A 60 UFP. Do you have these parts? Thank you, Chris

Hey Chris, thanks for reaching out. Yes we should definitely have hubs and brakes for you, but there is no way to look up your trailer to know exactly what hubs/bearings/brakes you will need.
The best way to determine what hubs you need is with the casting number from your brake drum. Each drum should have a casting number right on the front so if you pull a wheel off you should be able to see it. Most of the time we can use that number to pull up your hub, bearing and brake info. Knowing the axle weight capacity also helps narrow things down. I'll also need to know your hub bolt pattern. Should be 5 on 4-1/2" but please confirm.
For example, if what you have is a standard 3,500 lb axle, you'd need the following:
- Hydraulic Brake Kit - Uni-Servo - Free Backing - Dacromet - 10" - Left/Right Hand - 3,500 lbs # AKFBBRK-35-D
- Easy Grease Trailer Hub and Drum Assembly for 3.5K Axles - 10" - 5 on 4-1/2 - Pre-Greased # AKHD-545-35-EZ-K
That said, we do have the master cylinder for your Model 60 drum brake actuator. For that you'll need the following:
- Replacement Master Cylinder Assembly for Dexter Model 60 and Aero 7500 Brake Actuators - Drum # T4395100
Feel free to shoot me that hub info when you get a chance. I'm happy to look into it and confirm exactly what parts you need.
What kind of boat are you trailering?

Do you folks provide the labor to fix my boat trailer seals, brakes & bearings if needed. Or do you just sell the parts?
