Whether you're on the job or off-roading through the wilderness, it doesn't take long for rocks and other debris to wreak havoc on the body of your truck. LUVERNE Textured Rubber Mud Guards are the perfect solution for maintaining that pristine, professional look. For the front or rear of the truck, these custom mud flaps add style and body protection. They are constructed from heavy-duty black rubber that stands up to road debris and sheds water with ease. They feature 18-gauge stainless steel plates to help protect the bottom edge and extend the life of the mud flaps. With their 3/8" thick, recycled rubber construction, Textured Rubber Mud Guards easily deflect everything from mud to gravel, protecting the body of your truck from scratches, chips and scuffs. They are also made to add a stylish accent to your truck, featuring stainless steel plates along the bottom edge of each flap. The plates are made from 18-gauge stainless steel to provide a heavy-duty, rust-resistant shield, and they feature a bright, high-polish finish for a long-lasting shine. The textured finish of the rubber mud flaps is also designed to easily hide minor scuffs and scratches and maintain a clean appearance. For an easy installation and a custom fit, these truck mud flaps are made vehicle-specific. This particular set fits specific years of the Ford F350 Super Duty and F450 Super Duty (see application info to verify fitment). They install with corrosion-resistant fasteners and high-strength steel mounting brackets with a galvanized finish for long-lasting durability. Universal mud flaps are also available.

LUVERNE has manufactured truck accessories in the United States since 1963, specialising in grille guards, running boards, side steps and mud guards for pickups, commercial vans and SUVs. Products are built primarily from stainless steel, aluminium and mild steel, with model-specific mounting kits that use existing frame locations for a bolt-on installation.
LUVERNE has been manufacturing automotive accessories in the United States since 1963, and six decades of continuous production have made it a nationally recognised name in the truck accessory market. Now a Lippert brand, it concentrates on a defined set of products rather than spreading across the whole aftermarket: front-end protection, step access and spray protection for pickup trucks, commercial vans and sport utility vehicles.
Step products are the largest part of the catalog and the range is unusually deep, because the right step depends on the vehicle's ride height, the width of the rocker panel and how often people get in and out. The O-Mega II six-inch oval steps give a wide, flat standing surface in polished stainless or black powder coat, while the Regal 7 seven-inch oval steps go wider still for full-size crew cabs and lifted trucks. The broader running board and side bar range covers round tube, oval and boxed profiles across cab configurations, with treads positioned at the door openings where they are used.
Grille guards protect the front end against impacts, brush and road debris, built in tubular stainless or steel with model-specific brackets that tie into factory frame mounting points. Because the fit is engineered per vehicle, installation is a bolt-on job that does not require drilling or cutting on most applications.
Rounding out the line, LUVERNE mud guards and mud flaps shield rocker panels, paint and following vehicles from stones and road spray, in widths matched to the tyre and fender they sit behind. Material choice runs through everything the brand does: stainless steel where appearance and corrosion resistance matter most, aluminium where weight is the priority, and mild steel with protective coating where strength and value lead. Customers include contractors, fleet operators, van upfitters and truck owners.

No. The Model 251724 is designed specifically for dual wheel trucks. The manual does not confirm compatibility with single wheel configurations.

The kit includes: support bracket (Item #11), nylon washer (Item #9), four U-nuts (Item #8), four 1/4-20 × 1-1/4" button head screws (Item #5), four 1/4" fender washers (Item #7), one 1/4-20 serrated flange nut (Item #6), and one 7mm SEMS screw (Item #10).

The manual does not specify required tools. You will need standard hand tools to remove factory fasteners and install the mudguard hardware, but specific tool requirements are not documented.

The support bracket (Item #11) is installed using the factory bolt with a nylon washer between the bracket and vehicle body metal. It provides a mounting point for one of the mudguard fasteners and helps position the mudguard against the wheel well flange.
The nylon washer (Item #9) is placed between the support bracket and vehicle body metal to protect the vehicle's finish and prevent direct metal-to-metal contact when the factory bolt is reinstalled.
Four U-nuts (Item #8) are installed into the four outboard fender flare holes with threads facing toward the rear of the vehicle. These U-nuts accept the button head screws that secure the mudguard to the fender liner.
The U-nuts (Item #8) must be installed with threads facing toward the rear of the vehicle. This orientation allows the button head screws to thread into them from the front.

One 1/4-20 × 1-1/4" button head screw (Item #5) with a 1/4" fender washer (Item #7) passes through the mudguard and support bracket, then attaches with a 1/4-20 serrated flange nut (Item #6).
Four 1/4-20 × 1-1/4" button head screws (Item #5) with 1/4" fender washers (Item #7) pass through the mudguard and fender liner into the four U-nuts (Item #8) previously installed in the outboard fender flare holes.
