Fastway Flash SCALE Ball Mount: 4" Drop, Built-In Tongue Weight Scale, Dual Ball (48-00-8400)

Part Number: 48-00-8400

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.

Balance Before You Tow

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.

Is this the right model?

Choose the 48-00-8400 if you want built-in tongue weight visibility and your setup requires a 4" drop.

If you need more drop, move to the 6" or 8" SCALE models. If weight measurement isn’t necessary, the FLASH Secure series offers integrated locking instead.

R&P Knowledge Hub

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.
