Peterbilt 389 Full Fenders

Frequently Asked Questions About Peterbilt 389 Full Fenders

What are full fenders and how are they different from half fenders?

Full fenders cover the entire wheel and tire assembly from front to back, providing more complete coverage against mud, road debris, and spray than half fenders, which only cover the top portion of the wheel. Full fenders are a popular choice for drivers who want a classic look combined with maximum protection for the truck body and nearby equipment.

Will these fenders fit my Peterbilt 389 without modification?

Full fenders in this category are designed to fit the Peterbilt 389 chassis, but exact fitment can vary depending on wheelbase, tire size, suspension setup, and whether your truck has any custom modifications. It's a good idea to check the product listing for specific fitment notes and reach out to our team if you have questions about your particular configuration before ordering.

What materials are these fenders made from, and how do they hold up over time?

Full fenders are commonly available in materials such as steel, aluminum, and fiberglass, each offering different benefits. Steel and aluminum tend to hold up well against impacts and vibration, while fiberglass offers a lighter weight option with a smooth finish. The right choice often depends on your priorities around durability, weight, and appearance, so consider how the truck is used day to day when selecting a material.

How difficult is it to install full fenders on a Peterbilt 389?

Installation typically involves mounting brackets and hardware that attach the fender to the frame or existing fender supports. Many customers with mechanical experience are able to install these themselves using basic tools, but the process can take some time to ensure proper alignment and clearance from the tire. If you're not comfortable with the install, a truck shop or dealership can typically complete the job efficiently.

Do full fenders affect tire clearance or require adjustments for larger tires?

Because full fenders sit close to the tire for maximum coverage, tire size and suspension setup can affect clearance. If you run larger tires or have modified your suspension, it's worth double checking the fender's clearance specifications or contacting us to confirm the fit will work with your specific tire and wheel combination before purchasing.
