The Dexter Marine Model 660 is a premium hydraulic surge brake actuator designed for marine environments. Built for trailers with disc brakes, this actuator provides reliable, automatic braking power without the need for an in-cab controller.
Constructed with high-quality galvanized steel, it offers superior corrosion resistance against salt and freshwater. This model is a direct replacement for the Tie Down Engineering Model 660, making it the ideal upgrade for boat trailers and utility trailers requiring a 6,600 lb GVWR rating.
