13″-15″ Vented Hub and Rotor Assembly – 5 Bolt, 1,875 lb Capacity

Reliable Vented Hub and Rotor for Smooth, Safe Braking

The Hitchworks vented hub and rotor assembly is a strong, dependable option for your trailer’s disc brake system. It’s built from solid cast iron for long-lasting durability, making it a great fit for cargo, utility, and boat trailers.

This assembly replaces Shoreland’r #4410291 and supports up to 1,875 lbs per hub, or 3,750 lbs per axle. It’s made to handle tough loads while providing smooth braking and better heat control, thanks to its 9.75″ vented rotor. Because of its ventilated design, it cools faster than solid rotors—helping reduce brake fade during frequent stops or long downhill runs.

Made for Marine Use and More

You can use this vented hub and rotor in marine environments with confidence. Its cast iron construction holds up well, and it’s compatible with both standard bearing grease and VAULT lubrication systems. However, if you use it in saltwater, be sure to rinse it with fresh water afterward to extend the rotor’s life.

The rotor fits trailers with 13″ to 15″ wheels and 1-3/8″ x 1-1/16″ tapered spindles. It includes pre-installed races, so all you need are the bearings and seal to complete the setup.

Fast Install, Secure Fit

With its 5 on 4.5″ lug pattern and 1/2″ wheel studs, this rotor is easy to install on most standard trailer wheels. Its 1.980″ hub bore gives you a tight, smooth fit for consistent rotation and long-term reliability.
