Our line of noise and vibration dampening material, RoadKill Ultimate, combines the benefits of Stinger’s line of Expert aluminum/butyl material and Overkill acoustic foam.

With the RKU8, we've removed a step that many audio installers are currently taking—applying two different materials on top of each other for added insulation and noise damping. Not only are audio builds sounding better, but they’re also being completed more efficiently with outstanding audio definition. RoadKill Ultimate is the best solution to reduce a massive amount of unwanted resonating noise including but not limited to: panel vibrations, road noise, exhaust, engine noise & vibration—all of which degrade audio quality. Having a build designed and installed with RoadKill Ultimate allows the audio system to sound even louder and with more clarity and definition.

  • Improves overall audio frequency response and bass output
  • Kills panel resonance, squeaks and rattles
  • Self-adhesive for easy installation
  • Use on all metal panels, doors, roof, floor, firewall & trunk
  • Highest damping vs. weight ratio of any material available
  • Waterproof
  • 8 sq-ft total: 2 Pack (18” x 32”) noise deadening material

RoadKill Ultimate DNA

  • Acoustic foam outer layer that absorbs and diffuses high frequency sounds, acts as a thermal barrier, and absorbs sound waves that are otherwise trapped inside the empty space behind door panels.
  • Aluminum middle layer helps with heat dissipation.
  • Proprietary, ultra-dense butyl blend bottom layer absorbs acoustical energy that causes unwanted rattles and reduces vibrations.
