What are fenders on a truck? Essentially, they’re the large, protective covers positioned over the wheels. These shields are designed to prevent rocks, mud, and other debris from being thrown up by the tires.
As trucks drive, tires can easily kick up harmful materials, and that’s where fenders come in. By acting as a barrier, they help protect both the truck and nearby vehicles from potential damage.

Why Do Trucks Need Fenders?
Think of fenders as your truck’s bodyguards. They protect:
- The body: They prevent rocks and branches from scratching the paint and denting the metal.
- The tires: They shield your tires from flying debris that could cause punctures.
- The passengers: They keep mud and water from splashing onto you and your passengers.

Types of Truck Fenders
There are two main types of fenders:
- Front fenders: These are located at the front of the truck. They protect the front tires and the engine compartment.
- Rear fenders: These are at the back of the truck. They protect the rear tires and the bed.

For example, some trucks have fender flares that widen the stance of the truck and provide extra protection. Others may have mud flaps that help to prevent mud and debris from being sprayed onto other vehicles.
