Custom-Cut Kits

Custom-cut sound-deadening kits arrive cut to fit your vehicle's panels before they ship, so you can get straight to peeling, sticking, and rolling. No measuring, no trimming, no guesswork, and no pile of offcuts on the garage floor. Every kit here is Dynamat Xtreme, the same butyl and 4-mil aluminum constrained layer damper used in professional installs, cut to the panel instead of sold by the sheet. Browse over 170 precut sound-deadening kits below, grouped by make, model, and model year.

How Vehicle-Specific Sound-Deadening Kits Are Made

Each kit starts with the shape of your vehicle’s panels. The floor pan, transmission tunnel, inner door skins, trunk floor, and wheel wells are templated to create pieces that fit within the panel edges and leave factory openings and mounting points accessible.

Made-to-fit sound deadening gives you a clear starting point, but rolling each piece firmly onto clean, bare metal creates the bond that makes it work. As the panel vibrates, the butyl layer deforms and converts some of that energy into a small amount of heat, reducing the resonance you hear inside the cabin. Lifted edges and air pockets weaken that contact.

You can get the same result by cutting your own pieces from bulk sheets. It takes a template, a blade, and patience. Precut kits handle the measuring and cutting for you. Less installation time. Less material waste. Every kit uses Dynamat Xtreme made in the USA.

Sound-Deadening Kits by Vehicle

Find sound-deadening kits by vehicle, with collections organized by model and year range. The lineup includes American classics such as Mustang, Camaro, Firebird, Chevelle and other GM A-body cars, Corvette, Tri-Five Chevy, and Mopar A-, B-, and E-body models. Modern options include Tesla Model 3 and Model Y, Jeep Wrangler, Ford Bronco, and Dodge Challenger.

Trucks are covered, too. The truck collection has a sound-deadening kit for truck floors and four-door cabs on the 2021+ Ford F-150.

Check the model years and body style listed on each kit before you order. Kits often span several years, such as the 1968-1972 Chevelle/Malibu range, so match your vehicle to the product listing.

Dynamat is continuously developing new kits for more vehicles. So check back often.

Coverage by Area

Most builds get treated one area at a time, and the kits are split the same way. Pick the sound-deadening kit for car doors, floors, or the trunk based on the noise you want gone.

Car Door Sound-Deadening Kit

Vibration in the door panels adds rattles and resonance that compete with your speakers. A car door sound-deadening kit treats the metal panels to address that vibration, so you hear more of your music and less of the door.

Start with car door sound deadening if audio quality is your main complaint. For wind noise, check the seals and alignment first.

Car Floor Sound-Deadening Kit

Road, tire, and drivetrain vibration travels through the floor pan and transmission tunnel. A car floor sound-deadening kit treats these panels to kill the resonance that adds to cabin noise at highway speed.

Check each car floor sound-deadening kit for coverage details. Under-rear-seat treatment is sold separately for some vehicles.

Trunk Sound-Deadening Kit

The trunk and rear wheel wells amplify vibration from the road or a subwoofer. A trunk sound-deadening kit damps those panels, reducing the booming resonance behind the rear seats. Check the trunk and cargo kits for the areas covered, as trunk lids and package trays can have their own kits.

Some platforms also have roof kits. The firewall and engine bay take bulk material rather than a precut kit, so plan that area after the doors and floor.

Installing a Dynamat Custom-Cut Kit

Every Dynamat custom-cut kit is peel and stick. Once you’ve removed the trim to access the panels:

Clean and degrease the metal, then let it dry completely.
Test-fit each piece before peeling off the release liner.
Position the piece on its matching panel.
Roll it firmly onto the metal, working out air pockets for full adhesive contact.

A roller helps you get a firm, even bond. Find one in the tapes and tools collection, along with DynaTape for covering seams and exposed foil edges. For your first install, watch these Dynamat installation videos to see the process in action.

No Kit for Your Vehicle Yet?

If your vehicle isn’t listed, use bulk sheets to get the same Dynamat Xtreme and cut the pieces yourself. To estimate how much material to buy, use our sound-deadening product calculator.

Frequently Asked Questions

A custom-cut kit is templated to specific panels on a specific vehicle, so the pieces fit without measuring or trimming. Bulk sheets are sold by the square foot, and you cut them yourself. Kits win on installation speed and reduced waste for the areas they cover. Sheets give you more flexibility for odd shapes, partial coverage, modified panels, and vehicles without a kit. Plenty of builds use both.

Find your make and model, then check the year range in the kit title. Many kits cover several model years within the same body generation. Confirm the body style and panels included in the kit on the product page before ordering. If you’re unsure which kit matches your vehicle, contact us before ordering.

Start with what bothers you most. Floor kits reduce panel resonance from road, tire, and drivetrain vibration, so start there if the car gets loud at highway speed. Door kits tackle panel vibration that muddies your music, so start there if the stereo sounds thin or the doors buzz at volume. For wind noise, check the door seals and alignment first. You can treat both areas first, then tackle the trunk, firewall, or roof based on where noise remains.

The pieces are cut to target the areas where damping is most effective, not necessarily edge to edge. Full coverage is not required to reduce panel resonance, so kits leave clearance around panel edges, ribs, drain holes, and mounting points. Additional coverage can help, but the gains diminish as you add more material (and more weight and cost).

Not much. A degreaser and a clean rag to prep the bare metal, plus a roller to press each piece firmly against the panel and work out air pockets. The kits are peel and stick, so there is no adhesive to mix or spray. A utility knife helps with small adjustments around brackets, and DynaTape covers seams. The tapes and tools collection has the roller and tape.

No. Kits are cut per order, which makes them final sale. Check the make, model, and year range on the kit page before you order, and get in touch if you’re unsure whether your vehicle is included. Bulk sheets and other stock items follow the standard return policy.

Dynamat Xtreme bulk sheets let you cut the material to fit your panels. Remove the carpet or trim, make cardboard templates, and cut each piece to shape. Start with the areas you want to treat, such as the floor, doors, or trunk, and allow a little extra material for offcuts.
