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.\u003c\/p\u003e\u003cp\u003eA 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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Dexter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e K99-Z85-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 876983011087\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 19.56 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 20 x 5.25 x 6.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTowing Capacity:\u003c\/strong\u003e 8000 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Bolt-on, standard coupler mounting holes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety Latch Pin:\u003c\/strong\u003e Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Zinc-plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Boat Trailer Brakes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the towing capacity of the Dexter K99-Z85-00 drum brake actuator?\u003c\/strong\u003e The Dexter K99-Z85-00 is rated for an 8000 pound towing capacity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does this actuator mount to my trailer?\u003c\/strong\u003e It is a bolt-on unit that uses standard coupler mounting holes, so K99-Z85-00 installs without modifying the trailer tongue.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the K99-Z85-00 include a safety latch pin?\u003c\/strong\u003e Yes, a stainless steel safety latch pin is included to secure the coupler to the hitch ball.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of this brake actuator?\u003c\/strong\u003e The Dexter K99-Z85-00 measures 20 x 5.25 x 6.5 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the K99-Z85-00 weigh?\u003c\/strong\u003e It weighs 19.56 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material or finish protects this actuator from corrosion?\u003c\/strong\u003e The K99-Z85-00 has a zinc-plated finish, which resists corrosion in wet, salt-exposed boat trailer environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this actuator have a shock dampener?\u003c\/strong\u003e Yes, a shock dampener is built directly into the master cylinder of the K99-Z85-00 to absorb surge shock and reduce jolting during braking.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I bleed the hydraulic system on this actuator?\u003c\/strong\u003e The K99-Z85-00 includes an easy bleed system designed into the unit to simplify removing air from the hydraulic line during servicing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does this actuator use an oversized master cylinder?\u003c\/strong\u003e The oversized master cylinder design in the K99-Z85-00 produces higher braking pressure, giving faster and smoother stops when towing at or near the 8000 pound capacity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the K99-Z85-00 a complete drum brake coupler assembly?\u003c\/strong\u003e Yes, it is a complete bolt-on hydraulic drum brake actuator and coupler assembly, part number K99-Z85-00.\u003c\/p\u003e","brand":"Dexter","offers":[{"title":"Default Title","offer_id":48991265915099,"sku":"DEX-K99-Z85-00","price":474.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/t-d-82403_lg__53689.1687188021.500.750.jpg?v=1785189024","url":"https:\/\/www.goodvibesmarina.com\/products\/8-000-lb-bolt-on-hydraulic-drum-brake-actuator-for-boat-trailers-zinc-plated-built-in-shock-dampener-stainless-latch-pin","provider":"Good Vibes Marina","version":"1.0","type":"link"}
