The rotor uses UFP’s Zinc+ corrosion-resistant conversion coating — a multi-stage zinc-based finish that provides significantly greater corrosion protection than standard zinc plating alone. The aluminum caliper body reduces unsprung weight while the stainless steel hardware package addresses the most corrosion-prone fastener points in the assembly. This kit is the value-oriented alternative to the stainless rotor version, suited to trailers where strong corrosion resistance is needed but a full stainless rotor is not required.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eZinc+ coated ventilated rotor — multi-stage conversion coating for enhanced corrosion resistance\u003c\/li\u003e\n\u003cli\u003eAluminum caliper body — lightweight and corrosion resistant\u003c\/li\u003e\n\u003cli\u003eStainless steel banjo bolt and bleeder screw\u003c\/li\u003e\n\u003cli\u003eStainless steel slider pins and brake pad guides\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant back plate for brake pads\u003c\/li\u003e\n\u003cli\u003eIncludes spacer bracket and hardware for mounting on Dexter axles\u003c\/li\u003e\n\u003cli\u003ePart number: K7181000 | Catalog SKU: 445-K7181000\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKit Includes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eZinc+ coated ventilated rotor\u003c\/li\u003e\n\u003cli\u003eAluminum caliper body, piston, and bracket\u003c\/li\u003e\n\u003cli\u003eStainless steel banjo bolt and bleeder screw\u003c\/li\u003e\n\u003cli\u003eStainless steel slider pins and brake pad guides\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant brake pad back plate\u003c\/li\u003e\n\u003cli\u003eSpacer bracket for Dexter axle mounting and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eUFP by Dexter hydraulic disc brake systems on boat trailers\u003c\/li\u003e\n\u003cli\u003eUFP by Dexter hydraulic disc brake systems on utility trailers\u003c\/li\u003e\n\u003cli\u003eDexter axle installations requiring the spacer bracket configuration\u003c\/li\u003e\n\u003cli\u003eTrailers where Zinc+ corrosion protection meets the service environment requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThe K7181000 is the practical choice when you need solid corrosion protection at a lower price point than the full stainless rotor kit.
