Hello Jared,

Thank you for the additional information on the weight and what kind of brakes you have.

Everything matches up with the Demco Hydraulic Brake Actuator w/ Drop - Drum - Zinc - 2-5/16" Ball - 8,000 lbs # DM8759411, it is rated for 8K, drum brakes, and 2 5/16" ball. Without knowing the model number of what you are replacing, you will want to check the bolt hole dimensions. I attached an image for you to use as reference.

The # T4747200 you were looking at is for disc brakes, if it matches up better to what you are replacing you will want the # T4079200 for drum.

What kind of trailer is this going?
