Discover these Fibertech OE-style fiberglass front fenders designed for Peterbilt 388 and 389 models. Built from 1/4-inch thick fiberglass, these aftermarket replacement fenders are engineered to match original factory styling while offering a lightweight alternative to traditional steel components. Each set includes both driver and passenger side fenders and comes with built-in polymer liners to help protect against road debris and wear. Designed with a pre-drilled, OE-style fit, these fenders are made for straightforward installation without requiring major hood modifications or additional hardware. The smooth fiberglass surface ships in primer and is ready to sand, prep, and paint for a custom or factory-matched finish. Backed by a warranty against defects in workmanship and materials, they offer a practical balance of durability, fitment-focused design, and clean styling for compatible Peterbilt trucks.
