Upgrade your Peterbilt 379 with stainless steel 4-inch cab and sleeper panels designed for 1987-2007 models. Manufactured from high-quality stainless steel, these aftermarket exterior panels are built to provide a clean, polished look while offering corrosion resistance. Designed as 4-inch wide standard straight cab panels, they mount below the cab and help create a smooth visual transition between the cab and sleeper area. Available in configurations depending on application, these panels are typically sold as a complete set and are made in the USA. A manufacturer warranty against defects in workmanship and materials is included, making them a reliable choice for drivers looking to refresh or customize their exterior. Fitment should always be verified due to model-specific variations across Peterbilt 379 configurations.
