Peterbilt 379 Mud Flaps

Frequently Asked Questions About Peterbilt 379 Mud Flaps

Will these mud flaps fit my specific year Peterbilt 379?

Our Peterbilt 379 mud flaps are designed to fit all model years from 1987 to 2007. The mounting brackets and dimensions are consistent across these years, so you can order with confidence. However, if your truck has aftermarket fenders or custom modifications, we recommend measuring your current setup or contacting our support team with photos to ensure proper fitment.

What's the difference between rubber and stainless steel backed mud flaps?

Rubber mud flaps are the most economical option, offering good protection and flexibility in extreme temperatures. They typically last 2-3 years with regular use. Stainless steel backed mud flaps feature a polished or brushed metal plate bonded to heavy-duty rubber, providing superior durability and a premium appearance. While they cost more upfront, they often last 5+ years and maintain their appearance better, making them popular with owner-operators who want their rigs looking sharp.

Do I need special tools or hardware to install these mud flaps?

Installation typically requires basic hand tools including a drill with metal bits, wrenches, and a measuring tape. You will need to purchase bolts separately depending on your specific setup. The entire installation usually takes 30-45 minutes per side. If you're mounting to existing brackets, it can be as simple as removing old bolts and installing new flaps.

How do I choose between 24-inch and 30-inch wide mud flaps?

The width depends on your tire configuration and state regulations. Single tire setups typically use 24-inch wide mud flaps, while dual tire configurations require 30-inch or wider. Some states mandate specific coverage requirements - for example, mud flaps must extend to within 8 inches of the ground and cover the full width of the tires. We recommend checking your state's DOT requirements and measuring your current setup before ordering.

Can I get custom logos or designs on my mud flaps?

Yes, we offer several customization options. Our standard mud flaps come plain or with embossed Peterbilt logos. For custom graphics, we can add vinyl decals, reflective lettering, or LED light bars. Custom embossing is available for orders of 100 sets or more. Keep in mind that heavily customized mud flaps may have longer lead times of 2-3 weeks compared to in-stock options that ship within 1-2 business days.
