We can get you everything you need to go from hydraulic drum brakes to an electric over hydraulic set up for your trailer and 2005 GMC Sierra 2500. You'll need an EOH actuator, breakaway kit, and brake controller that is compatible with an EOH set up. First, for the actuator and breakaway kit you'll need the following:

- Dexter DX Series Electric Over Hydraulic Brake Actuator for Drum Brakes # K71-650

- Bright Way Push-to-Test Trailer Breakaway Kit # 3802311

Then for the brake controller & harness for your '05 Sierra that is compatible with an EOH set up, the best controller is from Tekonsha:

- Curt Assure Trailer Brake Controller # C49UR

- Curt Custom Wiring Adapter # C51352

If your truck has the factory 7-way, you're all set up and don't need anything else for the brake controller. But if you don't have the 7-way, you'll need one of two harness. If you have no connector at all, there will be loose wires above the spare, and you would need to hardwire in the Pollak 7-Pole, RV-Style Trailer Connector Socket w/ Wiring Harness # PK11898.

Or, if your truck has a round plug with a cap instead of a bundle of wires above the spare tire, use part # 30955.

First you will need to remove the old hydraulic equipment. Remove the surge coupler or actuator, remove all the lines, and finally remove the brake assemblies. If you have 10 inch diameter hub and drums, you may need to replace those as well. If you…

The dimensions you have are nearly identical to the CE Smith #CE19504-2 you looked at. However, these are designed for 14" wheels. For 15" wheels you would need the Fulton #F008585-2. These are slightly longer and taller at 10-1/4"…

Not confusing at all. I took a look online and the 2001 Silverado 2500HD has a 12,000 lbs bumper pull towing capacity and a 15,200 lbs 5th wheel towing capacity. It's just two different capabilities of the truck. The extra weight of a 5th wheel…
