Protect your catalytic converter with our easy to install undercarriage alarm. Simply mount the alarm with its 30lb force magnet to any flat portion of the frame on the vehicle. Any vibration detected beneath the vehicle will trigger the alarm and produce an ear piercing siren sure to get everyone's attention.
Unlike other alarms, Guardian alarms have a solid aluminum case to protect from heat, shock and the wear and tear you expect to find under your vehicle.
Each alarm comes with detailed instructions, keychain remote, and a "Protected by Guardian Undercarriage Alarm" sticker to warn thieves that your vehicle is protected.
