How to Soundproof a Truck

The truck floor can transmit road noise and heat from the drivetrain, making it one of the largest sources of interior noise. Start by treating the areas closest to where you sit. You’ll be targeting the truck floor, the doors, and rear cab wall.

In our guide on how to insulate a truck floor, we explain the process of applying a deadener and a sound blocker together for maximum results. Install Damplifier Pro™ to reduce vibration and deaden the metal. Then add a sound blocking layer, Luxury Liner Pro™, to block airborne noise entering the cab. Install at 100% coverage from the cabin-side firewall through to the back wall.

Doors can also transmit vibration and outside noise. Many truck owners use our kit to soundproof car doors along with this guide explaining how soundproofing car doors works. It follows the same two-step process of deadener + insulation.

A complete Truck Soundproofing Kit can simplify treating multiple areas at once.

Engine noise and heat often enter the truck through the firewall and hood. Powerful engines call for the best material and install.

You’ve got the cabin side of the firewall handled, but you can also install firewall heat insulation to help reflect radiant heat and clean up the sound of your engine. Read more about it in this guide on how to install truck firewall insulation.

Next, treat the hood to reduce engine noise making its way into the cab. Many truck owners install under hood insulation following this guide on how to upgrade truck hood insulation.

For heavy engine noise and heat, Mega Block™ is commonly used. For curvier, hoods, Heat Wave Pro™ is best.

Wheel wells are one of the biggest sources of road noise in pickup trucks because of the big tires. Road noise often comes directly from the tires, so learning how to quiet the noisy tires is important for truck drivers. Tire noise, road debris, and vibration from the suspension transfer directly into the body.

Apply our car soundproofing spray in three 1mm thick layers with 60 minute dry times between coats. To get the complete bundle with the bottle and gun, get Spectrum™ Wheel Well Sound Deadening Kits. For a detailed walkthrough, see how to sound deaden truck wheel wells

If you end up ordering more Spectrum than just the 1 gallon for the wheel wells, you can also treat the underside of the truck. This guide explains how to sound deaden the undercarriage of your truck.

Truck roofs are large flat panels that can transmit rain noise, wind noise, and heat from the sun. Treating the roof helps reduce these effects and makes the cab more comfortable in hot weather. In fact, blasting the AC can reduce fuel economy by 25% according to government fuel-economy research.

Start by exploring options for automotive roof insulation. Many truck builds combine sound deadening with absorption materials such as Mega Zorbe™ to control sound reflections in the cab.
