The Dexter K99-066-00 DX6.6 is a hydraulic surge brake actuator designed for trailers equipped with drum brakes. This robust actuator automatically applies braking force when the trailer pushes against the tow vehicle during deceleration, providing reliable and responsive braking performance without requiring electric brake controllers.

Key Features:

• 6,600 lb maximum capacity for mid-weight trailer applications
• Drop-N-Go coupler design with auto-latch feature that automatically engages when set on top of the hitch ball
• Fits 2-inch ball hitches for standard towing compatibility
• Zinc-plated steel construction provides excellent corrosion resistance for marine and freshwater environments
• Mounts on 3-inch trailer tongue with precision mounting holes spaced at 3 inches and 1-5/16 inches
• Built-in solenoid plumbing eliminates the need to remove the solenoid for servicing
• Compact dimensions: 18-1/4 inches length × 5-1/2 inches height
