This guide helps identify common trailer wheel bearings, races, and grease seals by axle capacity and spindle measurements.

Choosing the right trailer tire is one of the most important decisions you can make for safety, towing performance, and long-term costs. Whether you're hauling an RV across the country, towing a boat to the lake, or moving equipment around a job site, understanding the difference between radial tires and bias ply tires can help you make the best choice.

Choosing the right trailer axle is critical for safety, performance, and load-carrying capacity. Whether you're replacing a damaged axle, upgrading your suspension, or building a new trailer, identifying the correct axle specifications ensures your trailer performs as intended and remains compliant with weight ratings.

If your trailer brakes aren’t engaging—or worse, they’re locking up or dragging—it’s not just annoying. It’s dangerous. Trailer brake systems are made up of electrical, mechanical, and hydraulic components, and when something goes wrong, pinpointing the issue fast is key to safe towing.

Whether you're upgrading an axle, replacing springs, or buying an entirely new trailer, understanding your trailer's load capacity is critical. Misunderstanding GVWR, GAWR, and axle ratings can lead to dangerous overloads, uneven wear, and even legal penalties.

Sustainability isn’t just about recycling—it’s also about choosing products that last longer, reduce waste, and require fewer replacements. For trailer owners, upgrading to eco-friendly, low-maintenance parts not only helps the planet—it saves serious time and money over the life of your trailer.

While all trailers serve the purpose of hauling something important, the demands placed on a boat trailer vs. an equipment trailer couldn’t be more different. Whether you're towing jet skis or skid steers, the parts you use and the maintenance they require depend heavily on your trailer type.

Your trailer’s suspension system does more than cushion the ride—it protects your cargo, frame, and axle alignment from damage. But over time, leaf springs, equalizers, shackles, and spring hangers can wear out or break down. Left unchecked, these issues can lead to poor handling, uneven tire wear, or even catastrophic failure.

Wheel studs and lug nuts are small components with a big responsibility: keeping your trailer wheels securely attached at highway speeds, over bumps, through corners, and under heavy loads. When these parts fail, the results can be catastrophic—ranging from warped wheels to total wheel separation.

If you’ve ever had a trailer wheel seize up or start smoking on the road, there’s a good chance worn bearings or failed seals were the culprit. These small components take a beating—but with regular maintenance and timely replacement, you can avoid costly damage or dangerous breakdowns.
