Proper tongue weight is one of the most important factors for safe, stable towing—too little can cause dangerous sway, and too much can overload your hitch or vehicle. The FASTWAY FLASH SCALE™ Adjustable Ball Mount takes the guesswork out of towing by showing you your trailer’s tongue weight in real time with its built-in mechanical scale. In just seconds, you’ll know if your load is balanced correctly, giving you the confidence of a safer, smoother tow. With this instant feedback, you can adjust your cargo before you hit the road, protecting your trailer, your vehicle, and your family.

Achieving the correct tongue weight is essential for safe and stable towing. The tongue weight, which is the downward force exerted on the hitch ball by the trailer, should ideally be 10-15% of the total trailer weight. For example, a 5,000-pound trailer should have a tongue weight between 500 and 750 pounds. Maintaining this range ensures better steering, improved braking control, and reduced trailer sway, minimizing the risk of accidents. Too little tongue weight can cause the trailer to fishtail, while excessive weight can strain the tow vehicle and compromise handling. Using a tool like the FLASH™ SCALE Ball Mount, with its integrated mechanical scale, allows you to measure and adjust tongue weight effortlessly, ensuring your trailer is properly balanced for a safer, more confident towing experience.

What a FLASH Ball Mount Can Do For You

Ball mounts are the essential link between your tow vehicle and trailer. Their primary function is to hold the hitch ball securely and provide a solid, stable connection point for your trailer’s coupler. When inserted into the hitch receiver, the ball mount allows the trailer to pivot and follow your vehicle smoothly. They come in various configurations—fixed or adjustable height, and with different drop or rise measurements—to help ensure the trailer rides level with the towing vehicle. A properly leveled trailer improves towing control and reduces wear on tires and suspension. Ball mounts are built to handle specific weight ratings (called GTW – Gross Trailer Weight, and TW – Tongue Weight), so they’re a critical part of safe towing. For light to moderate loads, such as utility trailers, small campers, or boats, a standard ball mount is often all you need. Its job is to securely transfer the trailer’s tongue weight straight onto the rear of the tow vehicle without any extra complexity or moving parts.

What Ball Mounts Can’t Do For You

Despite being crucial for towing, ball mounts are not designed to manage weight distribution or trailer sway. They simply carry the tongue weight directly onto the vehicle’s rear suspension, which can cause problems if you’re hauling a heavier load. Too much weight on the rear axle can make the back of the vehicle sag and lift the front end slightly, which reduces traction, braking ability, and steering control. Ball mounts don’t do anything to counteract this. They also provide no sway control—so if crosswinds or passing trucks cause your trailer to fishtail, the ball mount alone won’t help stabilize it. That’s where weight distribution hitches come in. These systems use spring bars to spread tongue weight across all axles, restoring balance to the vehicle and making handling safer. Many weight distribution hitches also integrate sway control features to keep the trailer aligned during turns or wind gusts. In short, while ball mounts are great for basic towing, they offer no corrective measures for handling or stability issues caused by heavy trailers.

Easy To Install

The FLASH SCALE features a single-pin adjustment system that lets you swiftly set ball height—no tools needed, just pull the pin, slide to your desired height, and lock it in. It’s a fast, user-friendly setup that saves time whether you’re hitching a trailer at home or adjusting height on the fly at a job site. There’s no fighting with heavy steel parts or trying to line up tricky components—just one quick motion and it’s ready to go.

Its lightweight, aircraft-grade aluminum design makes handling easy, especially when compared to traditional steel mounts that can be a pain to maneuver. You can install or remove it without help, and the low-friction finish helps prevent sticking or seizing over time. For added peace of mind, robust dual locking pin sets are available to keep the mount securely in place during travel—even across rough terrain or under heavy towing loads.

Engineered with compactness in mind, the FLASH SCALE (including 6″, 8″, or 10″ drop versions) tucks neatly under your truck or in your garage—no bulky components to deal with. It’s ideal for users who want all the functionality of a high-quality hitch without cluttering up limited storage space in their vehicle or workspace.

When not in use, its slim form factor and lightweight construction mean it doesn’t take up much space, and its polished finish ensures it stays in great shape even during storage. Unlike heavier, grease-covered hitches that require extra care or cleanup, the FLASH SCALE is easy to handle, stays clean, and can be quickly stowed away without hassle. Whether you toss it behind a seat or place it on a shelf, it won’t get in your way.
