Dasm Whisperer

*Z-Automotive Products will ship directly from the manufacturer* Meet the DASM Whisperer by Z Automotive. The intelligent little module ensures your 2025.5 and 2026 Jeep’s driver-assistance system stays perfectly in sync, no matter what size tires you roll on. It quietly “Whispers” the original tire size to the DASM, so you never lose features like adaptive cruise or emergency braking after a tire upgrade. Just plug it in and drive with confidence.
