Find parts for your boat trailer

Shopping for brake parts for a RangerTrail (Ranger), EZ Loader, ShoreLand’r, BoatMate, Marine Master, Load Rite or Venture trailer? Start by identifying the brakes and hubs installed on your trailer.

This collection features Dexter DB-35 parts, also known by the older UFP name. Match each replacement to your existing part number and specifications. Trailer brand alone does not confirm fitment, and these parts are not universal across every model or year.

My original part says UFP. Where do I start?

Older DB-35 components and listings may use UFP or UFP DB-35 branding. This hub uses Dexter DB-35 as the current name. Compare the original part number and product specifications; branding alone does not confirm compatibility.

What should I check before replacing a caliper?

Look for a part number or casting mark, then confirm the mounting arrangement, caliper style and left/right application. Send us clear photos of the caliper and its markings if you need help matching it.

Are all DB-35 hub, bearing and seal parts the same?

No. Check the axle identification, rotor diameter, wheel bolt pattern, bearing numbers and seal dimensions against the product listing. The diagram above is a 3.7K reference, not a fitment guide for every DB-35 configuration.

What information helps you identify my parts?

Send the axle identification label, existing part numbers, and photos of the complete assembly and the part you need. Include measurements for a hub or seal, and the side of the trailer for a caliper.
