Where to apply B-Quiet Automotive Sound Deadener

B-Quiet’s most popular automotive sound deadening product is called Ultimate Automotive Sound Deadener which will help dampen interior cab noise and reduce vibrations.

To install Ultimate you must remove the seats, carpet pad, panels from the walls and bunk area and apply the peel and stick Ultimate directly onto all metal surfaces (floorboards, roof, cabin walls, doors and dash panels). The process is very simple and will only take about 3-4 hours.

The doors and dash panels can also be easily removed to apply Ultimate. To do this, the interior panels need to be removed. 

Installation Process

  1. Prepare the Surfaces: Remove seats, carpet pads, and panels from the floor, cabin doors, and bunk area.
  2. Apply the Material: Place sound deadening sheets directly onto the exposed metal surfaces.
  3. Doors & Dash Panels: Remove the door and dash panels, then apply the material inside to block vibrations and rattling.

This DIY upgrade is simple, effective, and designed for durability.

Benefits Beyond Noise Reduction

Sound deadening in a Freightliner isn’t just about reducing cabin noise. It also:

  • Improves driver comfort during long hauls.
  • Reduces fatigue by creating a quieter, calmer driving environment.
  • Adds thermal insulation, helping regulate cabin temperature year-round.

These extra benefits make it a worthwhile upgrade for both professional drivers and fleet owners.
