Frequently Asked Questions About Peterbilt 375/377 Windshield, Wiper & Roof Acc.

Will these windshield, wiper, and roof accessories fit my Peterbilt 375 or 377?

Products in this category are designed to fit the Peterbilt 375 and 377 model trucks. However, cab configuration, production year, and prior modifications can affect fit, so it's important to check the fitment notes listed on each product page and compare them to your truck's specifications before ordering. If you're unsure, our sales team can help confirm compatibility using your VIN or model details.

What materials are these parts made from, and how well do they hold up to weather and road conditions?

Depending on the specific item, you'll find components made from stainless steel, aluminum, chrome-plated metal, or durable rubber and polymer materials used for seals and wiper components. Stainless and chrome parts are chosen for their resistance to corrosion and everyday wear, but like any exterior part, they'll perform best with regular cleaning and care, especially in areas with heavy road salt or harsh weather.

Do windshield and roof accessories in this category help reduce wind noise or water leaks?

Many products, such as windshield trim, seals, and roof-mounted accessories, are designed to fit closely against the cab to help minimize gaps where wind and water can enter. Proper installation plays a big role in how effective these parts are at reducing noise or leaks, so following the included instructions or having a professional install them is recommended for the best results.

Can I install these parts myself, or should I have a professional do it?

Some accessories, like visor trim or small brackets, are straightforward enough for an experienced DIYer with basic tools. Others, particularly windshield-related components or larger roof accessories, may require more specialized tools or experience to install correctly and avoid leaks or damage. If a product involves adhesives, sealants, or drilling into the cab, we recommend professional installation or at minimum reviewing the manufacturer's instructions closely beforehand.

Are these parts OEM or aftermarket, and does that affect quality or fit?

This category includes both OEM and aftermarket options. OEM parts are built to match factory specifications exactly, while quality aftermarket parts are manufactured to fit and function similarly, often at a more affordable price point. Each product listing specifies whether the part is OEM or aftermarket, so you can choose based on your budget and preference for factory-matched fit versus cost savings.
