Peterbilt 387 Front Fenders & Acc.

Frequently Asked Questions About Peterbilt 387 Front Fenders & Acc.

What materials are Peterbilt 387 front fenders available in?

Front fenders for the Peterbilt 387 are typically available in fiberglass and steel. Fiberglass fenders are lightweight, resistant to corrosion, and easy to repair if cracked or chipped, making them a popular choice for many owner-operators. Steel fenders offer added durability and impact resistance but weigh more and can be prone to rust if the finish is damaged. Choosing between the two often comes down to weight preference, budget, and how the truck is used.

Will these fenders fit my specific Peterbilt 387 without modification?

Most fenders listed in this category are manufactured to match the original fender shape and mounting pattern used on the Peterbilt 387. However, fit can vary slightly depending on the model year, cab configuration, and whether the truck has factory or aftermarket brackets already installed. We recommend checking the listed specifications and comparing them to your existing fender or hardware before ordering to avoid fitment issues.

Do these fenders come primed, painted, or unfinished?

Fenders are commonly sold unpainted or in a gel-coat/primed finish, allowing you to paint them to match your truck's color. Some listings may offer a smooth, paint-ready surface while others may require additional prep work such as sanding or priming before painting. Always check the product description for finish details so you can plan for any additional bodywork.

What hardware or brackets do I need to install a replacement fender?

In most cases, you will reuse your existing fender braces, brackets, and mounting hardware unless they are damaged or you're upgrading to a different fender style. Some fenders are sold as a fender-only piece, while others may include mounting brackets or hardware kits. It's important to inspect your current brackets for cracks, rust, or wear before reinstalling them on a new fender.

How do I know if I need a full fender or just a fender extension or splash guard?

If your original fender is cracked, missing, or significantly damaged, a full replacement fender is usually the right choice. However, if the main fender structure is still in good shape and you're only dealing with mud, debris, or minor splash issues, a fender extension or splash guard accessory may be sufficient. Reviewing the specific damage or need on your truck will help determine which product fits your situation best.
