UFP by Dexter – Stainless Ventilated Rotor & Aluminum Caliper Kit
This UFP by Dexter rotor and caliper kit pairs a stainless steel ventilated rotor with a Zinc+ coated aluminum caliper assembly for a complete disc brake upgrade or replacement on compatible boat and utility trailers. The Zinc+ conversion coating delivers significantly greater corrosion resistance than standard zinc plating alone — an important advantage in saltwater and high-humidity trailering environments. All hardware in the kit is stainless steel or corrosion-resistant to match.
Key Features
- Stainless steel ventilated rotor for superior heat dissipation and corrosion resistance
- Zinc+ coated aluminum caliper — highly corrosion-resistant finish for marine environments
- Aluminum caliper body reduces unsprung weight compared to cast iron
- Stainless steel banjo bolt and bleeder screw
- Stainless steel slider pins and brake pad guides
- Back plate for brake pads provides additional corrosion protection
- Includes spacer bracket for mounting on a Dexter axle, with hardware
- Complete kit — caliper body, piston, and bracket included

Parts Desk Insights
This kit is the right choice when both the rotor and caliper need replacement at the same time — common after extended saltwater exposure or when a caliper seizes and scores the rotor. The stainless rotor and Zinc+ caliper finish make this a meaningful upgrade over standard replacement parts in corrosive environments. Before ordering, confirm the kit matches your existing UFP disc brake axle configuration and rotor bolt pattern. Brake pads are not included and must be ordered separately to complete the service.
