Peterbilt 375/377 Sleeper Side Acc.

Frequently Asked Questions About Peterbilt 375/377 Sleeper Side Acc.

What kind of parts are included in this category?

This category covers exterior accessories that mount to the sleeper side of Peterbilt 375 and 377 trucks, including sleeper side panels, fairings, storage boxes, access doors, and related trim and mounting hardware. These parts are used to replace worn or damaged factory components or to add extra storage and a finished look to the sleeper area.

Will these parts fit both the 375 and 377 models, or are they model-specific?

Many sleeper side accessories are designed to fit both the 375 and 377 due to their shared cab and sleeper platform, but panel shapes, mounting points, and box dimensions can vary depending on sleeper length and configuration. Always check the fitment notes on each product listing and compare measurements to your truck before ordering, especially if your sleeper has a non-standard length or custom setup.

What materials and finish options are available?

Sleeper side panels and boxes are commonly available in aluminum or steel, with finish options that may include raw/unpainted, painted, or diamond plate textures depending on the specific product. Aluminum options are generally lighter and more resistant to corrosion, while steel options may offer added durability. Check each listing for the exact material and finish since options vary by part.

Do these accessories come with mounting hardware, and how difficult is installation?

Most sleeper side panels and boxes include the necessary brackets or hardware for installation, but this can vary by manufacturer and product type, so it is worth confirming before you order. Installation typically involves basic hand tools and bolting the new panel or box into the existing factory mounting points, making it a manageable job for most shops or experienced DIY installers. Some larger storage boxes or fairings may require an extra set of hands due to size and weight.

Can I paint these parts to match my truck, and do they come pre-painted?

Some panels and boxes are available pre-painted or in a finish that matches common factory colors, while others are sold raw or unpainted so they can be finished to match your specific truck. If color match is important to you, check the product description to see whether the part is paint-ready or already finished, and plan for paint and prep work accordingly if it is not pre-finished.
