Peterbilt 389 Glider Full Fenders

Frequently Asked Questions About Peterbilt 389 Glider Full Fenders

Will these full fenders fit my Peterbilt 389 Glider without modification?

These fenders are designed to match the factory fender well and wheelbase dimensions of the Peterbilt 389 Glider, so most units bolt on using the original mounting points and hardware locations. That said, variations in axle configuration, wheel size, and prior aftermarket modifications can affect fitment, so it is a good idea to confirm your truck's specific axle spacing and tire size before ordering.

What material are these fenders made from, and how does it hold up over time?

Full fenders in this category are typically offered in materials like fiberglass or steel, depending on the specific listing. Fiberglass options tend to offer a smooth factory-style finish and resist denting, while steel versions provide added durability against impacts. Check the product description for the exact material, since maintenance and long-term durability differ between the two.

Do these fenders come primed, painted, or unfinished?

Most full fenders are sold either gel-coated (for fiberglass) or primed (for steel), ready for paint to match your truck. Very few come pre-painted to a specific color due to the wide range of Peterbilt paint codes. Plan on final paint matching or clear coating as part of your installation process.

What tools or experience do I need to install full fenders on a Peterbilt 389?

Installation generally involves removing the factory fenders, positioning the new fender assembly on the existing brackets or hardware, and securing it with bolts. Most installers with basic hand tools and mechanical experience can complete the job, but because these fenders are large single-piece units, having a second person to help with positioning and alignment during installation is recommended.

Are these fenders a direct replacement, or will I need additional brackets and hardware?

Many full fender kits include the mounting hardware needed for installation, but this varies by product. Some kits are fender-only and require reusing your existing brackets or purchasing separate mounting hardware. Review the product listing carefully to see what is included before you order, and reach out to us if you are unsure what your specific setup requires.
