Hydraulic Surge Couplers

TextModel DA91 is a heavy duty surge brake actuator for trailers with two or four wheels. When brakes are applied on the towing vehicle, forward inertia of trailer toward towing vehicle applies brakes on trailer in direct relation to manner brakes are applied on towing vehicle. Brake towing vehicle hard and brakes on trailer are applied hard.  Master cylinder push rod spring assembly protects system from hydraulic pressure overload.

Atwood Hydraulic Surge Brakes add safety and convenience to trailer towing.  Less complicated than other systems, the Atwood brake system provides such benefits as no "in car" hook up, no hand controls, and no special car to trailer wiring.  These features, plus automatic braking, smooth performance and simple operation are combined to provide a low cost, convenient brake system.

The Titan MD-60 coupler has a 6,000 pound capacity (max. G.V.W.R.) and 600 pound tongue load.  It is designed for a 3” wide trailer tongue.  The unique adjustable feature allows it to fit either an 1 7/8” ball or a 2” ball.
