What exactly is included in this category?

This category covers exterior sheet metal and panel components for the Peterbilt 387, including cab panels, sleeper box panels, and cowl panels (the section of the body just below the windshield, around the wiper area). These are structural and cosmetic body pieces used to repair rust, collision damage, or corrosion on the truck's exterior.

Will these panels fit my specific Peterbilt 387 configuration?

Panel fitment can vary based on your truck's sleeper length, cab style, and production year, since the 387 was built with different sleeper configurations over its production run. Always check the listed specifications and measurements against your truck before ordering, and reach out to our team with your VIN or truck details if you're unsure about compatibility.

What material are these panels made from, and how do they compare to OEM?

Most replacement cab, sleeper, and cowl panels are made from steel or aluminum, matching the material used in the original Peterbilt construction for that section of the truck. Quality can vary between manufacturers, so check product descriptions for gauge thickness and finish details, such as whether the panel is bare metal, primed, or pre-painted.

Do these panels come pre-painted or do I need to paint them myself?

Panels are typically sold unpainted or primed only, which allows you to match your truck's specific paint color during installation. If a panel is listed as pre-painted or finished, this will be noted in the product description; otherwise, plan on paint and bodywork as part of your installation.

Is installation something I can do myself, or does it require a body shop?

Simple bolt-on panels may be manageable for someone comfortable with basic bodywork and hand tools, but panels that require welding, cutting out rusted sections, or precise alignment with surrounding body lines are often best handled by an experienced truck body shop. If you're replacing a structural or load-bearing panel, professional installation helps ensure proper fit and long-term durability.
