While there are a few die-hards left in the Mopar world, most of us by now have a newer Mopar car or truck we use as a daily driver, saving our classic Mopar for the weekend car shows, cruising, or occasional track duty. Though we'd all like to drive our classic cars more often, they just don't seem to be as comfortable or quiet riding as our newer vehicles, and they are simply more tiring to drive, so they often remain parked. There are several reasons our old cars wear us out quicker when we go driving, including stiffer suspensions and fewer creature comforts, but a major cause of driver fatigue has been shown to be cabin noise. That's right--the constant drone of road and wind noise simply wears out the driver and passengers in the vehicle, making them irritable and cranky. And we don't have to tell most of you how unpleasant a car ride can be with an irritated family. Another reason these cars can get uncomfortable is because the heat of the engine, exhaust, and drivetrain is transferred through the floor and firewall, making for a sticky ride. Fortunately, these problems can be alleviated by insulating your Mopar properly and using modern noise, thermal, and vibration dampening materials.

Back in the '60s and '70s when most of our classic Mopars were built, noise and vibration dampening weren't on the top of the list when it came to automobile manufacturing. Thankfully, the Chrysler engineers were busy designing powerful engines and bulletproof drivetrains, making our cars some of the most desirable muscle cars of the era, but very little attention was paid to making these cars quiet to ride in. Mopars were as good as other cars at the time, with rubber door and window seals and a little insulation behind the firewall and under the carpet to keep heat out of the passenger compartment, but by today's standards the insulation and vibration and sound dampening in these old cars is woefully inadequate, making for a noisy, and often sweltering ride.

Actually, there are more ways for noise and heat to get into the cabin of your Mopar than you've likely considered. While door and window seals are some of the items we often replace, remember that sound and sometimes heat can also sneak around the trunk seal, the cowl seal at the rear of the hood, and even through the floor and carpet, especially if the car is missing body plugs or has worn window whiskers. Fortunately, companies like YearOne are reproducing most of the original seals and insulation found in our old Mopars, and the aftermarket parts are made from modern materials often making them better than the ones installed when our cars were new. So the first step in getting our old Mopar riding quietly is to install, restore, or replace all of the factory seals, body plugs, and insulation in our cars, ensuring the car is at least as quiet and insulated as when it left the factory. But to really reduce the noise and vibrations in our old cars, additional, modern dampening material can be used as well.
