Peterbilt Front Fenders

How to Choose the Right Peterbilt Front Fender

Replacing your Peterbilt front fenders, whether you own a 379, 389, or classic 359 model, is one of the most impactful ways to enhance the look of your rig. Whether you need an OEM replacement or a custom fender design, you can find it at Big Rig Chrome Shop. Here are a few considerations before making a purchase, including the material, finish, and sidewall depth:

• Fiberglass: The go-to for custom looks. It allows for seamless, molded shapes like wide lips, deep sidewalls, and ribbed designs. It is easy to paint and repair, but can crack under heavy impact.
• Aluminum: Lightweight and highly durable, aluminum is ideal for vocational trucks or those wanting a high-polish mirror finish. If it gets hit, it dents rather than shatters, but custom shapes are more limited.
• Stock / OEM Style: Usually features a minimal lip. Best for standard fleet trucks or those running on rough job sites where maximum tire clearance is required.
• Medium Drop (4" to 6" Sidewall): The perfect middle ground. Gives the truck a customized, lowered appearance without completely sacrificing turning clearance on uneven terrain.
• Low Rider (8.5"+ Sidewall): For the show trucks and highway haulers. These sit very low over the tire for an aggressive "bagged" look.
• Single Wall: The standard fiberglass shell. It's lighter and cheaper, but rocks thrown by the tire can create "star cracks" in your top paint job over time.
• Double Wall / Built-in Liner: Features a second layer of fiberglass or a protective liner underneath. It costs more up front (e.g., Peterbilt 379 Double Wall Front Fender), but it protects your expensive custom paint job from light impacts.
