Upgrade your truck with premium Peterbilt 379 rear fiberglass fenders engineered specifically for durability, clean body alignment, and long-term road performance. Whether you’re replacing cracked OEM components or completing a full custom build, our rear fenders for the Peterbilt 379 are designed for direct fitment and professional results.

Our 379 rear fenders are manufactured using reinforced fiberglass construction that delivers strength without unnecessary weight. Compared to steel or factory plastic alternatives, fiberglass offers improved corrosion resistance, easier repairability, and a smooth surface ideal for paint matching. These features make fiberglass the preferred choice for owner-operators, fleets, and show truck builders alike.

Designed for Direct Fit – Peterbilt 379 Compatibility

Each Peterbilt 379 rear fender is built to align with factory mounting configurations and common suspension setups. Proper fitment ensures clean wheel clearance, stable installation, and a consistent body line that complements the 379’s classic profile.

Before ordering, confirm:

• Model year of your Peterbilt 379
• Rear suspension and wheelbase configuration
• Mounting hardware compatibility

If you’re unsure, our team can assist in confirming the correct 379 rear fender option for your truck.
