Deflector Parts for trucks and semis

Deflector parts are key components of every truck and semi, designed to improve the aerodynamics and fuel efficiency of vehicles by reducing air resistance, also known as drag. They are usually installed on the exterior of trucks and semis and come in a wide variety of shapes and sizes to suit different vehicle configurations

There are many types of deflector parts, including side extenders, brackets, retainers, and more. Keeping all of them in good condition is crucial to make sure your truck is running properly and efficiently.

Types of deflector parts for trucks

Roof deflectors are a common type of deflector parts, which is mounted on the roof of the truck and helps direct airflow up and over the trailer, reducing drag between it and the cab. Side skirts are also commonly installed on the lower part of the trailer or the truck’s body to help streamline the airflow along the sides, preventing turbulent air from forming under your vehicle.

Air dams are often fitted to the lower front edge of the truck cab or semi-tractor, used to reduce the amount of air that flows underneath the vehicle, which can cause unwanted lift and drag. You can also mount gap fairings between the cab and the trailer to further reduce the air resistance, and attach rear fairings or tails to the back of the trailer to prevent the vacuum effect that is created when air leaves the rear of the truck.

Why maintain deflector parts?

Maintaining your deflector parts on trucks and semis is essential and can positively impact the performance, safety, and fuel efficiency of your vehicle.
