Why Does a Stock Harley-Davidson® Fairing Rattle and Muddy Your Audio?
A stock touring fairing is a hollow plastic shell wrapped around a stereo system, and hollow plastic vibrates. At highway speed, that vibration turns into rattle, buzz, and a stereo that sounds flat no matter how much you spend on speakers. Riders assume they need to replace the whole audio system to fix it. Most of the time, the problem isn't the speakers. It's the fairing acting like a drum around them.
Klock Werks, working out of Mitchell, SD, is the same shop behind the patented Flare® Windshield and limited-edition collaboration builds for Jack Daniels® and Indian® Motorcycle, and partnered with Dynamat, the industry-leading name in acoustic control, to build a kit that solves the actual problem instead of masking it. You can see the full lineup of kits by model on the Dynamat® collection page, where every fairing, saddlebag, and seat kit Klock Werks offers lives in one place.
What's Actually Inside a Klock Werks Dynamat® Sound Control Kit?
Every kit combines two materials, layered for a reason. Dynamat Xtreme, a butyl-and-foil composite, bonds directly to the inner shell of the fairing or saddlebag and adds mass that stops the plastic from resonating in the first place. Dynaliner, a closed-cell foam layer, goes on top to absorb the sound waves still bouncing around inside the cavity after the Xtreme layer has done its job. Used together, they treat vibration and echo as two separate problems instead of relying on one material to fix both.
How Does Dynamat Xtreme Reduce Vibration and Rattle?
Butyl rubber is good at converting vibrational energy into a small amount of heat instead of letting it travel through the panel as sound. The foil facing adds stiffness and mass to the plastic fairing shell, raising the frequency at which the panel wants to resonate well above the range your stereo and exhaust note actually produce. The practical result is less buzz, less rattle, and a cleaner signal reaching your ears.
How Do You Install a Dynamat® Sound Control Kit?
Every kit ships pre-cut to the exact contours of your fairing or saddlebag model. There's no template to trace, no scissors, and no leftover material to store or waste. You open the package, peel the backing, and press each piece into place. Most riders finish a fairing kit in under an hour using nothing more than the tools already needed to access the fairing liner.
What Do Klock Werks' Own Techs Hear After Installing Dynamat®?
The Krew doesn't take the difference on faith. Brian Klock, President and Visionary of Klock Werks, known industry-wide as the "King of the Baggers" and an inductee in the Sturgis Motorcycle Hall of Fame, points to a hallway test that happens more often than you'd expect.
"Ask the marketing department the difference it makes," Klock said. "Their office is adjacent to R&D. Before the Dynamat was installed, the AC/DC song the tech was playing on the stock system was fuzzy. After installation, the ladies in the office said they could make out the words of the song, and that kind of change in clarity from a stock radio can be heard, even through a wall."
Jennifer Bainbridge, Lead R&D Tech at Klock Werks, sees the same result from the install side, bike after bike.
"Whether you have a stock stereo or upgrades to your audio system, this sound control kit is going to improve your output," Bainbridge said. "It absorbs vibrations, concentrates the sounds, provides dampening for the radio components, and prevents echo through the fairing."

Where Can You Buy Klock Werks Dynamat® Sound Control Kits?

Get the Full Sound Out of Your Ride
A stock fairing was never engineered as an acoustic enclosure. It was designed to mount a windshield and house a stereo, not to control resonance, and Dynamat® Xtreme and Dynaliner close that gap in an afternoon. Race-tested, pre-cut, and proven on the lift in Mitchell, SD, this is the upgrade riders notice before they even know what changed.
As always, #GetKlocked 👊🏻
People Also Ask
Q: What is the difference between Dynamat Xtreme and Dynaliner?
A: Dynamat Xtreme is a butyl-and-foil constrained-layer material that bonds to the fairing or saddlebag shell and stops the plastic panel from resonating. Dynaliner is a closed-cell foam layer applied on top that absorbs remaining sound waves and reduces echo inside the cavity. Klock Werks kits use both together for a fuller result than either material would deliver alone.
Q: Will a Dynamat® kit fit my specific Harley-Davidson® or Indian® model?
A: Klock Werks cuts a separate kit for each major fairing and saddlebag platform, including Street Glide, Road Glide, and several Indian® touring models, across multiple model-year ranges. Always match your kit to your exact year and model on the product page, since fairing shapes change enough between generations that kits are not interchangeable.
Q: Can I install a Dynamat® Sound Control Kit myself?
A: Yes. Every kit ships pre-cut with instructions, and installation is a peel-and-stick process that most riders complete in under an hour using the tools already needed to access the fairing liner or saddlebag interior. No cutting or trimming is required.
Q: Does Dynamat® sound deadening add noticeable weight to my bike?
A: The material adds a small, distributed amount of weight to the inner fairing or saddlebag shell, not enough to be noticeable in handling or performance. The tradeoff is a stiffer, quieter panel in exchange for a few ounces of material you'll never feel while riding.
Q: Do I need to remove my entire stereo system to install the kit?
A: No. In most cases you only need to remove the fairing liner or inner panels to access the surface where the Dynamat® material is applied. The stereo components typically stay in place, though always check the specific install instructions for your model before starting.
