This is the left side caliper only; the right side is a separate part number, so confirm which side needs service before ordering. The kit ships as a complete assembly rather than a bare caliper, including the caliper body, mounting bolts, and a set of marine grade brake pads, so a single purchase covers the parts needed to restore stopping power on one wheel position without hunting down bolts or pads separately. The aluminum caliper body resists the corrosion that steel calipers are prone to in saltwater and brackish launch conditions, which is the main reason boat trailer brake components are built from aluminum rather than the cast iron common on automotive applications. The included marine grade pads are matched to the DB35 caliper and are rated for the same submersion and corrosion exposure the caliper itself sees during boat launching and retrieval. Because this is a left-hand specific kit, installing it on the right side of the trailer will not seat or align correctly, so buyers should verify the worn caliper's side before ordering a replacement. The kit is intended as a direct service replacement for the left-hand DB35 caliper on trailers within the 3.7K to 7K axle capacity range.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e UFP by Dexter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e K71-776-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Side:\u003c\/strong\u003e Left-Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliper Material:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrake Model:\u003c\/strong\u003e DB35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAxle Capacity Range:\u003c\/strong\u003e 3.7K to 7K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePad Type:\u003c\/strong\u003e Marine grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e Caliper assembly, mounting bolts, marine grade brake pads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 9.07 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 876983005826\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Boat Trailer Brakes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits DB35 boat trailer disc brakes on axles rated 3.7K to 7K, left-hand side only.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eIs the K71-776-01 for the left or right side of the trailer?\u003c\/strong\u003e The K71-776-01 is a left-hand specific caliper kit and should only be installed on the left side of the trailer; the right side uses a different part number, so confirm which caliper is worn before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat brake system does this caliper kit fit?\u003c\/strong\u003e This kit is built for DB35 boat trailer disc brakes on axles rated from 3.7K to 7K, so it is intended for that specific caliper and brake model rather than as a universal fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the K71-776-01 kit?\u003c\/strong\u003e The kit includes the caliper assembly, mounting bolts, and a set of marine grade brake pads, so no separate pad or hardware purchase is needed for a left-side caliper replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the caliper body made from?\u003c\/strong\u003e The K71-776-01 caliper body is aluminum, which is more resistant to saltwater corrosion than the steel or cast iron calipers used on automotive brakes.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre the brake pads included rated for marine use?\u003c\/strong\u003e Yes, the pads included with the K71-776-01 kit are marine grade, matched to the corrosion and submersion exposure a boat trailer caliper sees during launch and retrieval.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the K71-776-01 caliper kit weigh?\u003c\/strong\u003e The complete K71-776-01 kit weighs 9.07 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat axle capacity range is this caliper designed for?\u003c\/strong\u003e The K71-776-01 DB35 left-hand caliper kit is designed for axles in the 3.7K to 7K capacity range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this kit be used on the right side if I only have one bad caliper?\u003c\/strong\u003e No. The K71-776-01 is left-hand specific and will not align correctly on the right side; a matching right-hand kit is a separate part number and should be ordered for that side.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine UFP by Dexter part or an aftermarket copy?\u003c\/strong\u003e The K71-776-01 is a genuine UFP by Dexter caliper kit, not a generic aftermarket substitute.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the kit come fully assembled or do I need to build the caliper myself?\u003c\/strong\u003e The K71-776-01 is supplied as a caliper assembly kit with the caliper, bolts, and pads included, so it is ready to install as a left-hand unit rather than requiring separate component sourcing.\u003c\/p\u003e","brand":"Dexter","offers":[{"title":"Default Title","offer_id":48991264014555,"sku":"DEX-K71-776-01","price":237.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/Dexter-3500-7000lb-Left-Hand-Caliper-Replacement-Kit-K71-776-01__35875.1747363800.500.750.jpg?v=1785188213","url":"https:\/\/www.goodvibesmarina.com\/products\/ufp-by-dexter-db35-left-hand-aluminum-disc-brake-caliper-kit-k71-776-01-fits-3-7k-7k-marine-trailer-axles","provider":"Good Vibes Marina","version":"1.0","type":"link"}
