Did you know that there is an easier way to reduce tire noise in your Peterbuilt Truck, than driving at a slower speed and keeping your tires fully inflated? B-Quiet.com offers a range of automotive sound deadening products which can be used to lower low-frequency road, engine, tire and mechanical noise.
Why Peterbilt Trucks Need Sound Isulation
Even with solid factory construction, years of use and vibration make these trucks prone to interior noise. Common culprits include:
- Diesel engine vibration transferring through the firewall and floor.
- Road and tire rumble from long hours of highway driving.
- Wind turbulence hitting the roof, mirrors, and sleeper cab.
- Cab resonance caused by large, flat metal surfaces that act like amplifiers.
Inside the cab, this constant low-frequency hum can easily exceed 80-90 dB, enough to cause hearing fatigue after long shifts.
B-Quiet Automotive Sound Deadening
At B-Quiet.com you will find several automotive sound deadening products that can be easily applied to your Peterbuilt Truck to reduce noise.
An inexpensive option is B-Quiet Extreme Sound Deadener, which absorbs structural and mechanical vibrations from gears, engines, suspensions and the road, converting them into low level heat.
If you want to spend a bit more money, B-Quiet Ultimate Sound Deadening is recommended. Slightly thicker than Extreme, Ultimate offers better absorption for high vibration applications. Used throughout your Peterbilt Truck it will provide a great first layer of sound deadening that will do a good job at making your Peterbilt Truck quieter.
Best Sound Deadening Materials for Peterbilt Trucks
The B-Quiet Team recommend applying Ultimate on:
- The dash panels can be easily removed in order to apply it.
- To do the floorboards, the seats and carpet need to be removed. The process is very simple and will only take about 3-4 hours.
- Ultimate can be applied to the cabin walls and doors. To do this, the interior panels need to be removed, and Ultimate can be placed on all inside metal surfaces.
For full results, also use:
HLiner for the roof, engine bay, and hood liner.
VComp behind seats, bunks, and wall panels to dampen low-frequency vibration.
What Peterbilt Drivers Are Saying
Professional drivers on The Truckers Report Forum frequently share how much sound deadening transforms their driving experience.
One Peterbilt 389 owner mentioned:
One driver shared that applying insulation under the bunk and firewall cut vibration and engine heat significantly, making rest breaks far more comfortable.
Truckers also note that using VComp behind the sleeper walls and HLiner on the roof helps maintain steady temperature control and reduces A/C load during summer months.
Final Thoughts
Your Peterbilt is built for the long haul, make it comfortable enough to match its endurance.
Adding Ultimate, HLiner, and VComp to your cab and sleeper will reduce road noise, control heat, and create a quieter space to rest and drive.
