Diagram of Bumper Clearance for Rock Star mud flaps

Note: A minimum of 3" of clearance is needed from the edge of the bumper step to the end of the ball mount shank to ensure a proper fit. If the ball mount shank does not align with the hitch receiver so that the hitch pin can be inserted - or if the Rockstar's frame cannot be positioned to hang straight and plumb - a longer ball mount will be needed to install the mud flaps.

Protect Your Investment

Without mud flaps, traveling the rocky road to your favorite campsite or boat launch may lead to costly fiberglass repairs or a scratched up paint job on your towed boat, trailer, car, ATV, or snowmobile. Protect your investment with this stylish Access Rockstar mud flap system. These mud flaps shield what you tow and look great while doing it. Rockstar's hitch-mount design clamps onto your ball mount and the whole assembly simply slides into your hitch receiver. Openings in the frame allow you easy access to your hitch pin and trailer connector, and you can easily remove the flaps when you aren't towing.

Rockstar XL Mud Flaps

Rock Star Mud Flaps Comparison Chart with XL highlighted

The Rockstar hitch-mounted mud flaps come in 4 different sizes. These XL mud flaps (highlighted in the image above) provide much more coverage inward toward your ball mount than the standard flaps, and they extend 1" beyond the frame to offer great protection for your load against road debris.

Rockstar Looks and Custom Fit

Rear View of Rock Star Mud Flaps Hugging Bumper

Rockstar mud flaps just look cool on your truck. The smooth, shiny finish gives your vehicle a stylish look, and the frame hugs your bumper tightly for a from-the-factory fit. The mud flap length is designed to fit perfectly with the stock ride height of your truck, and the mud flaps have rounded top corners for a sleek appearance.

Bumper Flange for Rock Star Mud Flaps Resting on Bumper

The support flange on the frame is designed to fit your bumper step. These custom details make the Rockstar kit one of the best-looking mud flap setups on the road.

Heavy-Duty Construction

The beefy mud flaps are made of a 1/2" thick rubber for superior protection. These mud flaps stay in place better than thinner mud flaps because the heavy-duty rubber construction helps to prevent flapping in windy conditions. They stay down where you need them - protecting your valuable equipment from mud and flying rocks. The smooth rubber surface also reduces ice and snow buildup for a cleaner look.

Rockstar mud flaps can withstand temperatures of up to 250 F, so they won't be damaged by the heat from your exhaust. If you have a modified exhaust system that brings your exhaust outlet closer to the mud flaps, a heat shield (A80807 - sold separately) is available for added protection.

The frame is constructed of sturdy, lightweight, rustproof aluminum.

Easy Installation and Removal

You can install the mud flaps in a few simple steps. First, attach the included 2" x 2" ball mount clamp to the back of the custom frame using the included hardware. Slide your ball mount into the frame, and tighten the frame clamp loosely around the ball mount shank. Next, insert the ball mount into your hitch and secure it with a pin and clip. Adjust the frame until it sits level and plumb on your bumper. Adhesive discs (included) protect your vehicle from scratches where the frame comes in contact with the bumper. Finally, secure the frame to your ball mount by tighening the clamp with a torque wrench.

Once the frame is properly installed, attach the mud flaps to the frame using the included stainless steel screws.

To take off the mud flaps, simply remove your ball mount from your hitch receiver with the Rockstar frame still attached. You do not need to remove the flaps from the frame before removing your ball mount. The Rockstar mud flap assembly stays clamped to your ball mount for a quick installation the next time you need it.

Review from a similar Access Rockstar in Mud Flaps

Looks nice on truck, haven't backed it out of shop since I just installed over the weekend. Bolted up fairly easy to bolt up with the little women holding it plumb and level while I tighten nuts up. Will update after getting it out where I can get a look in the sunshine. 336737

Review from a similar Access Rockstar in Mud Flaps

This mud flap assembly worked perfectly in protecting our travel trailer from rock damage on our Alaska trip last summer - we had no damage to the trailer from flying debris during the 10,000 mile trip. I would highly recommend this assembly. My picture was taken towards the end of the trip. 635691
