  • Availability of 10,000 lb Axle Dexter Trailer Brake Assemblies
    The only option we have for 10k axle rated Dexter electric brake assemblies is the part # 23-438-439 that you referenced. 10k trailer axles with drum brakes just aren't as popular as other options so there isn't as much competition for this size.

  • Electric Drum Brakes for 10K Axle Conversion from Hydraulic Brakes
    Your choice of electric drum brakes to replace your hydraulics will be based on axle weight capacity.

These brakes work with wheels sizes...

  • Brake Assembly for Dexter 10k Axle with 12 1/4 x 4 Brakes
    I have a solution for you but part # AKEBRK-10 is not what you are looking for. Instead the Dexter Electric Trailer Brake Kit Left/Right Hand Assemblies part # 23-438-439 is the set you need. The others are just a little too narrow for your application.
