Shop Peterbilt 379 Half Fenders by Material

Completely customize the rear setup of your rig with Peterbilt 379 half fenders in poly, stainless, aluminum, and fiberglass.

Stainless Steel & Aluminum Half Fender Kits

Explore corrosion-resistant half fender kits, with mounting accessories included, from Hogebuilt, Vendetta, and Trux Accessories. For a high-end upgrade, we stock premium stainless steel rear tandem fender kits, and for a mid-range price point, we offer standard steel fenders (without bracket kits) in smooth, long-drop, or ribbed finishes. Choose from checkered or smooth aluminum-style half fenders for a lightweight and affordable aftermarket upgrade.

Poly & Fiberglass Half Fenders

Upgrade to a complete poly fender kit with super single options for a wider coverage area that guards the rear tires against road spray and debris. Fiberglass half fenders can be painted to match your cab, the perfect choice for show-truck builds. Filter by top-tier brands like WTI, Fibertech, and Talladega Fiberglass.

Half Fender Mounting Kits & Brackets for Peterbilt

Secure your fenders with heavy-duty mounting hardware built for the long haul. From suspension-specific hidden brackets to heavy-gauge steel tubes, find the exact structural hardware required to keep your half fenders securely attached to your Peterbilt 379 frame.

Peterbilt 379 Specific Bracket Kits

Eliminate the installation guesswork with exact-fit bracket kits. They feature bolt-on mounts that harmoniously integrate with with factory suspensions—including Low Air Leaf, Flex Air, and Air Trac—ensuring a rigid, drill-free fitment.

Universal Half Fender Mounts

Maximum versatility for custom builds. Explore adjustable mounting arms, swivel brackets, and weld-on kits built to adapt to stretched frames, modified suspensions, or mixed-fleet applications. It’s the perfect heavy-duty solution when a standard factory mount just won't cut it.

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.
