Surge-type actuator features a corrosion-resistant composite master cylinder and a primed finish. Bulldog Collar-Lok coupler provides tight, solid connection with hitch ball and is great for heavy-duty towing. Welds onto a 50-degree A-frame trailer.


Features:

  • Activates your trailer's drum brakes when tow vehicle slows or stops - no brake controller needed
  • Bulldog Collar-Lok coupler fits tightly around hitch ball for secure connection
    • Heavy-duty design is great for utility, livestock, cargo, and construction trailers
    • Pin-style fastener holds collar in place around base of hinged ball socket
  • Composite master cylinder is durable and efficient
    • Glass-reinforced nylon construction resists rust and corrosion
    • Large reservoir provides increased capacity for brake fluid
    • Automotive-style diaphragm cap creates completely enclosed system to help prevent contamination of fluid
  • Acetal copolymer lining provides smooth operation as actuator telescopes in and out
  • Built-in drop helps you match tow vehicle height
  • Breakaway included
  • Constructed of heavy-duty steel
  • Primed finish
  • Weld-on installation
  • Made in the USA


Specs:

  • Application: 50-degree A-frame trailers with hydraulic drum brakes
  • Ball size: 2-5/16"
  • Gross towing weight: 8,000 lbs
  • Maximum tongue weight: 800 lbs
  • Drop: 4"
  • Model number: DA91
  • 1-Year warranty


Note: Because this actuator does not include a reverse lockout, it is recommended that you equip your trailer with free-backing brakes so that you can drive in reverse without the actuator triggering your trailer's brakes.


When you apply the brakes in your tow vehicle, deceleration occurs and momentum pushes your trailer toward the rear of your vehicle. With surge brake systems, the hydraulic actuator is triggered as your trailer moves forward, once your tow vehicle starts to slow down. When this happens, the actuator contracts, applying force to its master cylinder. This in turn supplies the necessary hydraulic pressure to engage your trailer's brakes.
