ROCKSTAR Hitch Mounted Mud Flaps

If you want maximum trailer protection, you want ROCKSTAR™ 3XL Hitch Mounted Mud Flaps. The 3XL model extends 9 inches beyond the frame in addition to providing protection behind the tires and toward the center of the truck. These mud flaps are perfect for dually pickups and any driver who refuses to compromise when towing boats, campers and other trailers.

These massive mud flaps are cut from solid half-inch thick rubber. This hefty rubber resists sailing and can take a beating on the road, so expensive trailers stay shiny and clean. The rubber has a smooth surface to prevent ice and mud from building up and is capable of withstanding temperatures as hot as 250 degrees Fahrenheit.

The laser-cut aluminum frame is carefully shaped to match the contours of a pickup’s bumper. The system is held together by stainless steel hardware for dependable rust resistance.

Installation is straightforward. The frame’s clamping system fastens to a truck’s ball mount and the stabilizer plate keeps the mud flaps level with the bumper. The hitch pin is easy to reach through the frame’s opening and pulling the pin releases the entire mud flap system when not needed. When the mud flaps are needed again, vinyl-capped stops make a simple task of aligning the hitch and pin again.

Note: ROCKSTAR™ Hitch Mounted Mud Flaps are designed to fit OEM receiver hitches and bumpers and may not fit aftermarket products.

Great shield to protect what you are towing. We traveled over a great deal of road construction this summer & the trailer showed no stone chips or tar marks on it. We would recommend this product.
