The FLASH SCALE gives you real-time tongue weight feedback during hookup—eliminating guesswork and helping you tow balanced, stable, and confidently without separate tools.
Improper tongue weight is one of the leading causes of trailer sway and braking instability. The FLASH SCALE integrates a mechanical scale directly into the mount—allowing you to verify load balance instantly, before you ever leave the driveway.
Target Range: 10–15% tongue weight delivers stable, predictable towing.
Too Light: Increases sway risk and reduces control.
Too Heavy: Overloads suspension and impacts braking.
Why This Matters: The built-in scale lets you correct load balance before towing—not after instability appears.
