Steel vs. Aluminum Ball Mounts
The best ball mount material for your towing setup depends on what you want to tow, how often you want to tow it, and how frequently you change ball mounts. Aluminum's durability and light weight make it ideal for almost any towing situation. On the other hand, steel offers an incredible weight capacity and a lower price point. Read on below to determine which popular ball mount type is right for you. Here are some of our most popular ball mounts from Curt, Draw-Tite, Fastway, and Weigh Safe - all well-known names in the towing business.

Aluminum Ball MountsAluminum's resistance to rust and corrosion makes it ideal for wet or humid environments. If you live in an area with high humidity or make frequent trips to the water, an aluminum ball mount will hold up longer than a steel one. A common worry about aluminum ball mounts is that they are not as strong as steel and are therefore unsuitable for towing, but as long as the ball mount is rated for sufficient weight capacity to tow your trailer, an aluminum ball mount is just as capable of towing as a steel one. Aluminum mounts are also generally lighter than their steel counterparts. However, while aluminum ball mounts are perfectly capable of towing within their weight limits, they do not have the same hefty weight capacities as steel ball mounts. The GTW range for most aluminum ball mounts is between 8,000 and 21,000 lbs., so if you need a ball mount that can handle more weight, steel is the better option. Aluminum is also more expensive, so if you only tow occasionally, you might not want to spring for an aluminum mount.

Steel Ball MountsSteel is known for its incredible strength and weight capacity—the GTW range for most steel ball mounts is between 2,000 and 32,000 lbs. Steel ball mounts are also more cost-effective than their aluminum counterparts, so you have more weight capacity options at a lower price point. On the other hand, steel is heavy, so it can be difficult to frequently change ball mounts if you tow multiple trailers. Most steel ball mounts are protected by a corrosion-resistant powder coat, but this layer does wear down over time. Steel is far less resistant to rust than aluminum is, so if you live or tow in an environment where your ball mount will regularly be exposed to humidity, road salt, or saltwater, it's crucial to properly maintain your steel ball mount in order to minimize corrosion.
Did you know?
With steel and aluminum ball mounts of similar capacities, aluminum ball mounts can range from 5 lbs. to over 15 lbs. lighter than their steel counterparts.
Steel Maintenance and Rust Prevention In order to maximize your steel ball mount's longevity, it's a good idea to routinely check for scratches and touch up any blemishes with rust-inhibiting spray paint (available at your local hardware store). Removing the ball mount when not in use can also help prevent rust and damage. Ball mounts should be stored in a dry location out of the natural elements. A durable ball mount storage bag is an excellent way to store your ball mount and other towing equipment when not in use. Related ProductsRelated ArticlesWritten by: Amber S.
