Steel fenders offer durability and a traditional look, aluminum provides a lighter weight option with corrosion resistance, and fiberglass allows for custom shaping and a smooth finish. Each material has different maintenance needs, so consider your priorities for weight, appearance, and long-term upkeep when choosing.

Will full fenders fit my Peterbilt 379 without modification?

Most full fenders designed for the Peterbilt 379 are built to match the truck's factory wheelbase and axle configuration, but fitment can vary depending on tire size, suspension setup, and whether your truck has any aftermarket modifications. It's a good idea to check the product's listed specifications and compare them to your truck's measurements before ordering to avoid fitment issues.

What tools and steps are involved in installing full fenders?

Installation typically involves mounting brackets or hardware to the frame or axle, then securing the fender in place with bolts. Basic hand tools such as wrenches and sockets are usually sufficient, though some setups may require drilling or additional bracket fabrication depending on the fender style and your truck's existing hardware. Reviewing the installation instructions included with your specific fender before starting the job is recommended.

How do I maintain full fenders to prevent rust or damage?

Regularly washing off road salt, mud, and debris helps extend the life of your fenders, especially for steel components that are more prone to rust. Inspecting mounting hardware periodically for looseness caused by vibration and road conditions can also help prevent cracking or fender loss over time. Fiberglass fenders should be checked for stress cracks near mounting points.

Do full fenders affect ground clearance or tire clearance?

Full fenders are designed to cover the wheel assembly more extensively than half fenders, which means tire size and suspension height can impact how much clearance remains between the tire and fender. If you run larger tires or have a modified suspension, double check the fender's clearance specifications to make sure there's no rubbing during turns or when the truck is fully loaded.
