Peterbilt 359 Sleeper Roof Acc.

Frequently Asked Questions About Peterbilt 359 Sleeper Roof Acc.

What kinds of products are included in this category?

This category covers sleeper roof accessories for the Peterbilt 359, including items such as roof fairings, roof caps, marker/clearance light bars, air deflectors, and related trim and hardware that mount to or along the top of the sleeper cab. These parts are designed to work with the shape and dimensions of the 359's sleeper roof.

Will these accessories fit my specific Peterbilt 359 sleeper configuration?

Because the 359 was built over many years and with different sleeper box lengths and roof profiles, fitment can vary between trucks. We recommend checking the listed dimensions and mounting details on each product page and comparing them to your truck's measurements before ordering. If you're unsure, reach out to our team with your truck's specs so we can help confirm compatibility.

What material and finish options are available?

Roof accessories in this category are commonly available in fiberglass, aluminum, or stainless steel, depending on the part. Finishes range from raw or primed fiberglass that can be painted to match your truck, to polished or brushed stainless for a chrome-like look. Product listings specify the material and finish so you can choose what fits your build and maintenance preferences.

How difficult is installation, and can I install these myself?

Most roof accessories mount using existing holes, brackets, or adhesive/sealant along with fasteners, and many owner-operators install them in their own shop or driveway with common hand tools. That said, working at cab height means proper ladders or lift equipment and a helper are strongly recommended for safety and to get straight, even alignment, especially on longer fairings or multi-piece roof caps.

Do I need to seal or weatherproof these parts after installation?

Yes. Any accessory that mounts to the roof and penetrates the surface for bolts or brackets should be sealed with a quality urethane or silicone sealant to prevent water intrusion into the sleeper. Even parts that use adhesive-only mounting benefit from a bead of sealant around the edges to keep moisture out and maintain a clean, finished look over time.
