Peterbilt 379 Quarter Fenders

Frequently Asked Questions About Peterbilt 379 Quarter Fenders

What material are Peterbilt 379 quarter fenders made from?

Quarter fenders for the Peterbilt 379 are typically available in materials such as stainless steel, aluminum, and fiberglass. Stainless steel offers durability and a polished look, aluminum provides a lighter weight option with good corrosion resistance, and fiberglass is often chosen for a smooth, paintable finish. The best choice depends on your priorities around weight, appearance, and long-term maintenance.

Will these quarter fenders fit my specific Peterbilt 379 configuration?

Quarter fenders are generally designed to fit the 379's frame and wheelbase, but fitment can vary depending on tire size, axle configuration, and whether you have single or dual wheel setups. Its important to check the product listing for specific measurements and compatibility notes, and to compare them against your trucks setup before ordering.

Do quarter fenders come pre-drilled for mounting, or will I need to drill my own holes?

This varies by manufacturer and product. Some quarter fenders arrive pre-drilled with mounting holes that align with common bracket setups, while others are sold undrilled to allow for custom fitment. Check the product description for details, and be prepared to do some measuring and drilling if the listing indicates a universal or unfinished fit.

What mounting hardware or brackets do I need to install these fenders?

Most quarter fenders require separate mounting brackets, which may or may not be included depending on the specific product. Common options include half-round or quarter-round brackets, along with bolts and fender braces. Its a good idea to review the listing closely or reach out to confirm what hardware is included versus what you may need to purchase separately.

How do I maintain the finish on my quarter fenders to prevent rust or corrosion?

For stainless steel fenders, regular washing and occasional polishing will help maintain shine and prevent water spots or surface corrosion. Aluminum fenders benefit from routine cleaning to avoid oxidation, especially in areas with road salt exposure. Fiberglass fenders should be inspected periodically for chips or cracks, and any exposed edges should be sealed or painted to prevent moisture damage.
