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.

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.
