Frequently Asked Questions About Peterbilt 375/377 Door & Cab Side Acc.

What products are included in this category?

This category covers door and cab side accessories for Peterbilt 375 and 377 models, including items such as door handles, hinges, mirror brackets, cab side panels, trim pieces, battery box covers, and related hardware that mount to the exterior door or cab side area of the truck.

Will these parts fit my specific Peterbilt 375 or 377?

Most parts listed are designed to match the factory fitment for the 375 and 377 model years, but cab configurations and production changes over the years can affect fitment. We recommend checking the listed part number, comparing it to your existing component, and reaching out to our team with your VIN or model year if you are unsure before ordering.

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

You will find both OEM and aftermarket options within this category. OEM parts are built to original factory specifications, while aftermarket parts are manufactured to match fit and function at a different price point. Material and finish quality can vary between brands, so check the product description for details on construction and coating before purchasing.

What finish and material options are available?

Depending on the specific item, you may find options in painted steel, stainless steel, chrome-plated, or raw finish. Stainless and chrome options generally offer better corrosion resistance for trucks that see a lot of road exposure, while painted or raw finishes may require additional coating or touch-up to match your cab color.

Do these accessories require professional installation?

Many door and cab side accessories, such as handles, hinges, and trim pieces, can be installed with basic hand tools by someone comfortable with general truck maintenance. More involved components, like items affecting door alignment or structural mounting points, may benefit from professional installation to ensure proper fit and function. If you are unsure, consult the product instructions or a qualified technician.
