Mack CV/GU Truck Exterior Parts

Frequently Asked Questions About Mack CV/GU Truck Exterior Parts

Will these exterior parts fit my specific Mack CV or GU model year?

Mack CV and GU trucks were produced across multiple years with some design changes to body panels, mirrors, and trim. Before ordering, check the fitment details listed on each product page and compare them to your truck's model year and configuration. If you are unsure, having your VIN or chassis information on hand will help you or our team confirm the correct part.

What materials are these exterior parts made from, and how do they hold up?

Exterior parts in this category are typically made from materials such as steel, aluminum, or durable molded plastic and composites, depending on the specific component. Metal parts generally offer more durability against road debris and impacts, while plastic or composite components are often used for fairings, trim, and lighter body panels to reduce weight. Product listings note the specific material used for each item.

Do these parts come pre-painted or finished, or will I need to paint them myself?

Finish varies by product. Some exterior parts ship primed or unpainted, requiring paint to match your truck's color, while others may come with a factory finish or protective coating. Always check the product description for finish details so you can plan for any additional paint or prep work before installation.

Are these OEM Mack parts or aftermarket replacements?

This category includes both OEM and quality aftermarket options. Aftermarket parts are built to match the fit and function of the original components and can offer a more budget-friendly alternative. Each product listing specifies whether the part is OEM or aftermarket so you can choose based on your preference and budget.

Can I install these exterior parts myself, or do I need a professional?

Many exterior components, such as mirrors, trim pieces, and fairings, can be installed with basic hand tools and general mechanical knowledge. However, larger parts like hoods, fenders, or structural body panels may require additional support, alignment, or professional installation to ensure proper fit and safe operation. If a part involves electrical connections, such as lighting, extra care should be taken to ensure wiring is correctly matched before installation.
