Frequently Asked Questions About Peterbilt 379 Half Fenders
What materials are Peterbilt 379 half fenders available in, and which is best for my truck?
Half fenders for the Peterbilt 379 are typically offered in stainless steel, aluminum, and durable plastic or poly composite options. Stainless steel is popular for its polished look and long-term durability, aluminum offers a lighter weight alternative with good corrosion resistance, and poly fenders are budget-friendly and resistant to denting. Your choice often comes down to the finish you want, how much weight you're comfortable adding, and your budget.
Will these half fenders fit my specific 379 model year and axle configuration?
Most half fenders in this category are designed to fit the Peterbilt 379 across its production years, but fitment can vary depending on axle spacing, tire size, and whether the truck has a single or tandem rear axle setup. Always check the product's listed specifications and measurements against your truck's setup before ordering, and reach out to our team if you're unsure about compatibility.
Do half fenders come with mounting brackets and hardware, or are those sold separately?
This varies by manufacturer and specific product. Some half fenders include the necessary mounting brackets, bolts, and hardware for installation, while others are sold as the fender shell only, requiring brackets to be purchased separately. Be sure to review the product description carefully so you know exactly what's included before you order.
How difficult is it to install half fenders, and can I do it myself?
Installing half fenders is a common DIY project for many truck owners with basic tools and some mechanical experience. The job generally involves mounting brackets to the frame or existing fender supports and securing the fender shell in place. However, precise alignment matters for both appearance and tire clearance, so if you're not comfortable with the process, having a professional installer handle it can help avoid rubbing or fitment issues.
How do I keep polished stainless steel or aluminum half fenders looking good over time?
Regular washing to remove road salt, brake dust, and grime is the most important step in maintaining the finish on stainless steel or aluminum fenders. For polished stainless, periodic use of a metal polish designed for truck chrome or stainless can help maintain shine and prevent oxidation. Avoid abrasive pads or harsh chemical cleaners, as they can scratch or dull the surface over time.
