Will these parts fit my specific Peterbilt 357 or 378?

Fitment can vary depending on the model year, cab configuration, and sleeper size of your truck. We recommend checking the listed specifications on each product page, including any noted year ranges or cab styles, and comparing them to your VIN or existing part numbers before ordering. If you are unsure, reach out to our customer service team with your truck's details so we can help confirm compatibility.

What materials and finishes are available?

Sleeper components in this category are typically available in materials such as aluminum, steel, or fiberglass, depending on the specific part. Finish options may include raw, painted, or polished surfaces. Check each product listing for the exact material and finish offered, as this affects both appearance and durability.

How difficult is installation, and can I do it myself?

Installation difficulty depends on the specific part. Some accessories, like small storage additions or trim pieces, may be straightforward for anyone comfortable with basic tools. Larger components, such as structural panels or boxes that involve mounting to the sleeper frame, may require more time, proper tools, and a good understanding of your truck's sleeper construction. If a product requires cutting, drilling, or welding, we recommend having it installed by someone experienced with truck bodywork.

Do these parts come with mounting hardware or instructions?

This varies by product. Some items include mounting hardware and instructions, while others are sold as the component only, requiring hardware to be sourced separately. Always check the product description for what is included in the box, and contact us before purchasing if this information is not clear.
