Dexter Hydraulic Drum Brake Actuator, Bolt-On Trailer Coupler, 8000 lb Capacity - K99-Z85-00

The Dexter K99-Z85-00 is a bolt-on hydraulic drum brake actuator built for boat trailers, rated for an 8000 pound towing capacity. It mounts using standard coupler mounting holes, so it installs in place of a compatible actuator without modifying the trailer tongue. The actuator uses an oversized master cylinder design that generates higher braking pressure for faster, smoother stops when towing at capacity.

A built-in shock dampener is incorporated directly into the master cylinder, absorbing surge shock and reducing the jolting that can occur during braking or backing up. An easy bleed system is built into the unit to simplify routine hydraulic servicing and air removal after fluid changes. A stainless steel safety latch pin secures the coupler to the hitch ball, and the housing carries a zinc-plated finish for corrosion resistance in the wet, salt-exposed conditions typical of boat trailer use.
