Solid and Durable

The cast iron drum feels super heavy-duty. I use my trailer for work and it gets a lot of abuse. These hubs and drums seem like they'll last for a long time.

Easy Install, No Issues

Installed these on a new axle from another brand and they fit perfectly. The 5 on 4.5 bolt pattern is a common size, so no problems there. Brakes work great now.

Good Value, Fast Delivery

Needed these in a hurry for a repair job. They arrived faster than expected. The quality for the price is fantastic, especially with the pre-installed races.

Great for a 3.5K Axle

Exactly what I needed for my small car hauler trailer. The build quality is top-notch, and the zinc finish looks like it will hold up well to road salt.

Perfect Replacement

My old drums were shot. These were a direct replacement for my Dexter axle. The new hubs and drums made a huge difference in braking feel. Great product.
