Peterbilt 330/335/337 AC Vents

Frequently Asked Questions About Peterbilt 330/335/337 AC Vents

What years and models are these AC vents compatible with?

These AC vents are specifically designed for Peterbilt 330, 335, and 337 models manufactured from 2005 to 2010. While some vents may physically fit newer models, we recommend checking your OEM and existing vent dimensions before ordering, as Peterbilt made minor changes to the dash configuration in 2011. The mounting tabs and screw hole patterns must match your existing setup for proper installation.

Are these OEM quality or aftermarket replacements?

We carry both genuine OEM Peterbilt vents and high-quality aftermarket alternatives. OEM vents are made from the same ABS plastic as your original parts and carry Peterbilt part numbers. Our aftermarket options use reinforced polymer construction that resists UV damage and warping better than some factory vents. Both options feature the same louver design and airflow capacity as your original vents.

How difficult is the installation process?

Installation typically takes 15-30 minutes per vent with basic hand tools. You'll need a trim removal tool or flat-head screwdriver to carefully pry out the old vent without damaging the dash. Most vents are held in place by 2-4 spring clips or screws accessible from behind the dash panel. No cutting or modifications are required. We recommend having a flashlight handy to see the mounting points clearly, especially for center dash vents.

What colors and finishes are available?

Standard colors include black, gray, and tan to match factory interior options. Black is the most popular and readily available. Gray typically matches 2007-2010 interiors, while tan works with earlier model year interiors. All vents feature a matte finish that resists fingerprints and glare. Chrome-accented bezels are available for some models but may require longer lead times.

Why do these vents break so frequently?

The factory vents use plastic louvers connected by thin pivot points that become brittle over time due to heat exposure and UV damage. Common failure points include the adjustment tabs and the louver hinges. Repeated adjustments and temperature cycling cause stress cracks. Our replacement vents address these issues with thicker pivot points and UV-stabilized materials. To extend vent life, avoid forcing stuck louvers and consider using dashboard UV protectant sprays.
