Truck Mud Flaps

Q: Are mud flaps required by law on pickup trucks?

Mud flap requirements vary by state. Many states require mud flaps or splash guards on larger vehicles and trucks — particularly on the rear wheels — to reduce road spray and protect other drivers. Some states only require them when towing. Check your state's specific vehicle equipment regulations. Regardless of legal requirements, mud flaps are strongly recommended for trucks used in work, hauling, or towing applications where road debris and spray are a constant factor.

Q: What is the difference between WeatherTech, Dee Zee, and Luverne mud flaps?

WeatherTech DigitalFit mud flaps are laser-measured, custom-fit to your specific truck model and year — no drilling required for most applications. They use a flexible, UV-resistant thermoplastic that won't crack in extreme cold. Dee Zee mud flaps are stainless steel or poly options built for heavy-duty commercial and work truck use, with a more rugged aesthetic and robust hardware. Luverne Textured Rubber mud flaps are molded rubber with stainless steel weight bars for a heavy, professional look that holds position even at highway speeds. Choose WeatherTech for a precise no-drill fit. Choose Dee Zee or Luverne for a heavier-duty commercial appearance and steel construction.

Q: What material are the best mud flaps made from?

The three most common materials are thermoplastic, rubber, and stainless steel. Thermoplastic (used by WeatherTech) is flexible, UV-resistant, lightweight, and won't crack in cold weather — ideal for year-round use in any climate. Rubber (used by Luverne) is heavy and holds position well at speed, providing a solid, traditional look. Stainless steel (used by Dee Zee) is the most durable and corrosion-resistant option — preferred for commercial work trucks in harsh environments where long service life matters more than weight.

Q: Will mud flaps interfere with running boards or side steps?

Rear mud flaps generally do not interfere with running boards or side steps since they mount behind the rear wheels. Front mud flaps on trucks with running boards occasionally require checking clearance at the front wheel well. Custom-fit mud flaps (like WeatherTech) are designed with knowledge of factory running board configurations and typically account for this. If you have aftermarket steps or nerf bars, confirm clearance on the product listing or contact us before ordering.

Luverne Mud Flaps

Luverne mud flaps use molded rubber construction with stainless steel weight bars along the bottom edge. The weight bar keeps the flap flat and stable at highway speeds without flapping or curling — a common problem with lighter mud flaps at 70+ mph. The textured rubber surface provides a professional, commercial appearance that matches well with chrome and stainless running board and nerf bar accessories. Available in vehicle-specific configurations for popular full-size trucks.

WeatherTech vs. Dee Zee vs. Luverne — Which Should You Choose?

Choose WeatherTech if you want a no-drill installation, a precise custom fit, and a clean low-profile look. Best for personal and work trucks where appearance matters and you don't want to drill into the body.

Choose Dee Zee if you run a commercial work truck or fleet vehicle and need the most durable, corrosion-resistant option available. Stainless steel construction holds up in salt, chemicals, and continuous heavy-duty use where thermoplastic options eventually show wear.

Choose Luverne if you want a heavy rubber flap with a weighted bottom edge that stays flat at speed and pairs well with stainless or chrome running board accessories. A good middle ground between the clean WeatherTech look and the commercial Dee Zee build.

Why Install Mud Flaps on a Work Truck?

Road debris kicked up by truck tires is significantly more damaging than what a typical car throws. Work trucks run heavier loads, often on unpaved job site roads, gravel, and construction zones — conditions that multiply the volume and velocity of rocks, mud, and road salt reaching the undercarriage, wheel wells, and following vehicles. Mud flaps address this directly:

Undercarriage and wheel well protection — Constant rock impact chips paint, damages wheel well liners, and accelerates rust on metal components behind the wheel. Mud flaps absorb and redirect that impact before it reaches the truck body.
Road salt and corrosion prevention — For trucks operating in northern climates where roads are heavily salted in winter, mud flaps reduce the volume of salt spray that reaches the rear frame, hitch, and trailer wiring connections.
Paint protection — Rocks thrown from front tires frequently chip the leading edge of rear wheel wells and the lower body panels behind the rear tires. A proper set of front and rear mud flaps significantly reduces this damage over the life of the truck.
Trailer and tow vehicle protection — When towing, debris thrown from the truck's rear tires hits the front of the trailer or tow vehicle directly. Rear mud flaps reduce this impact substantially.
Legal compliance — Several states require mud flaps or splash guards on trucks of certain GVWR ratings, particularly in commercial use. A set of proper mud flaps keeps you compliant without inspection issues.

Truck Mud Flap FAQs

Are mud flaps required by law on pickup trucks?

Requirements vary by state. Many states require mud flaps or splash guards on trucks — particularly at the rear wheels — to reduce road spray. Some only require them when towing. Check your state's vehicle equipment regulations. For commercial work trucks and fleet vehicles, mud flaps are strongly recommended regardless of legal requirements to protect the truck and stay compliant during roadside inspections.

What is the difference between WeatherTech, Dee Zee, and Luverne mud flaps?

WeatherTech offers laser-measured, no-drill thermoplastic mud flaps for a precise custom fit and clean appearance. Dee Zee builds in stainless steel and poly for commercial heavy-duty durability and corrosion resistance. Luverne uses molded rubber with a stainless steel weight bar for stability at highway speeds and a professional look that pairs well with running board accessories. See the brand section above for the full breakdown.

Do WeatherTech mud flaps require drilling?

Most WeatherTech No-Drill mud flaps use existing factory hardware points — no drilling required. Some vehicle applications may require drilling. Check the specific product listing for your truck's year and model to confirm before ordering.

Do mud flaps fit trucks with oversized or lifted tires?

Standard mud flaps are designed for factory wheel well clearances. Lifted trucks or trucks with oversized tires may need extended coverage options or a size check against actual wheel well dimensions. Contact our team if you're working with a modified truck and need help selecting the right fit.

What material are the best mud flaps made from?

Thermoplastic (WeatherTech) is lightweight, UV-resistant, and stays flexible in extreme cold. Rubber (Luverne) is heavy and holds position well at speed. Stainless steel (Dee Zee) is the most durable and corrosion-resistant — preferred for commercial work trucks in harsh environments. The best material depends on your use case: no-drill clean fit → WeatherTech; commercial durability → Dee Zee; weighted rubber look → Luverne.

Will mud flaps interfere with running boards or side steps?

Rear mud flaps generally don't interfere with running boards. Front mud flaps on trucks with aftermarket steps occasionally need a clearance check at the front wheel well. Custom-fit mud flaps like WeatherTech are designed with factory running board configurations in mind. If you have aftermarket steps, confirm clearance on the product listing or contact us before ordering.
