ROCKSTAR™ Full Width Tow Flap Customer Review Best on market. I have used several brands. Like this one for factory hole install, underneath truck to prevent sharp turn impact to towable item. Clean and good product.

Review by: Darin M. - MN   star star star star

ROCKSTAR™ Full Width Tow Flap Customer Review The flap seems to be high quality, and fits and looks nice.Mounting was a bit of a challenge. Unfortunately the directions and accompanying photos did not match with my truck in any way. An extra hour with a tape measure showed which bolts I needed to remove, then a trip to the hardware store for the correct length bolts to mount brackets. This was on a 2023 Ford F-150.Overall I'm pleased with the towflap in spite of installation challenges.

Review by: Victor B. - VA   star star star star star

Love it. Easy installation. Easy to take off and put back on. I did drill a pass thru hole so I could use a bolt and wing nut to take the flap apart for easy storage in back of my truck during camping trips when driving around not towing. I would highly recommend to anyone. Great product.

ROCKSTAR™ Full Width Tow Flap Customer Review We just went on a 1200 mile fishing trip. Over 100 of those miles were on Canadian gravel roads. I had my Rockstar Full Width Tow Flap installed and while the boat got dirty, it was no comparison to what it has been past times, and no rock chips! I love my tow flap and I convinced the other two boats to look into them as well.

Review by: Gerard W. - CA   star star star star star

Purchased full length adjustable Rockstar mud flap. Had an issue with one of the rubber flaps. Spoke to Melanie in customer service and she is what customer service is all about. Very helpful and completely went above and beyond my expectations. Way to go Melanie.

These things are way better Han anything I have wvever had they are very well built

Review by: David S. - NY   star star star star star

Product is high quality. Actually had a little weight to it. Easy to assemble, I found I just had to take my time and go over the instructions a couple times to make sure I had it all good. Product does a great job preventing dirt, mud and rock chips. When I'm done I just take it off and my dually doesn't have to have full time mud flaps.

Review by: Patrick P. - GA   star star star star star

Awesome product that works great. Easy to install and can be removed without much fuss..

Review by: Jon H. - OH   star star star star star

Very happy with purchase. Hardware was incomplete and customer service responded quickly with a replacement part.

Review by: Chris C. - ID   star star star star star

Nice product and easy to install. First use was good - kept the jet boat clean from the mud and dirt. Especially like how it tucks up under the bumper - not like those hitch mounted eyesores. Good job!

Review by: Timothy K. - VA   star star star star star

ROCKSTAR™ Full Width Tow Flap Customer Review Great product! It assembled easily and everything fit with no jiggling or hassle. It is a little heavy but I can get it on and off alone. The biggest problem is where to store it in my garage.

Review by: Chris M. - WA   star star star star star

Love it!! Easy to install!! Would definitely buy again!

Review by: Wayne M. - OR   star star star star star

Super easy assembly and installation. I like the ease of taking it off when not needed. Nice fit for my Super Duty with heat shield behind exhaust.

ROCKSTAR™ Full Width Tow Flap Customer Review Great product, it does rub on the bottom of bumper I put sections of heater hose on the area so it will not scratch my painted bumper.

Review by: Dion D. - SD   star star star star star

ROCKSTAR™ Full Width Tow Flap Customer Review this is the best tow flap i have ever owned. It is well constructed and easy to install and remove when not needed. One of the biggest advantages is that since it mounts under and ahead of the rear bumper, it doesnt affect my backup sensors. Huge safety advantage right there! thanks.

ROCKSTAR™ Full Width Tow Flap Customer Review RockStar Mud Flaps are a great replacement for our Rock Tamers. The RockStars are very easy to assemble and install. They also allow me to use the ProGate tailgate on my GMC Sierra 3500 without worrying about damaging the tailgate due to contact with the hitch bar that was supporting the Rock Tamers.

ROCKSTAR™ Full Width Tow Flap Customer Review Great replacement for my Rock Tamers. Easy to install and now I can use my Pro Gate on my GMC without worrying about damage to my Pro Gate from the hitch, which the Rock Tamers connected to.

ROCKSTAR™ Full Width Tow Flap Customer Review Man, I sure wish I would have known about this product YEARS AGO! The trailer I purchased had an option to add an air dam/rock guard to it, but that was a $700 plus add on. So I opted not to do it.Additionally, I really disliked the hitch mounted rock guard because most of them required a special trailer tongue. I already have a WeighSafe. For half the cost of an air dam AND I can utilize my existing hitch tongue, ROCKSTAR for the win! It saved the front of my Camaro from everything my truck blasted it's way.

Review by: Dennis B. - ND   star star star star star

ROCKSTAR™ Full Width Tow Flap Customer Review Absolutely love this product. Its on all the time. Because it's underneath the bumper, I can run it through a car wash VS the hitch mount style. I can change out my receiver hitches as needed for the boat or camper also because it's mounted underneath the bumper. If on the rare occasion I have to take it off it's super simple just pull 2 pins.

ROCKSTAR™ Full Width Tow Flap Customer Review I ordered the Full width tow flap with adjustable height. This product fit perfectly, the instructions were very straightforward which made installation very easy. great product!!

ROCKSTAR™ Full Width Tow Flap Customer Review Love these things. I pull my boat back and forth from Texas to Louisiana and after one trip without mud flaps I had tons of rock chips. I ordered these and they worked amazing. Definitely worth the investment and I love how you can remove it easily with 2 pins. Such an easy and well built system!

ROCKSTAR™ Full Width Tow Flap Customer Review I purchased this product, after looking at other brands, mainly for the design and craftmanship. I have to say I could not be happier. I use it to protect my camper while towing and it has performed flawlessly. I like it so much I'm buying another one for my new truck. Stop thinking about it, just buy one! you will not regret it.

ROCKSTAR™ Full Width Tow Flap Customer Review It's really nice having a flap that will provide protection to the front of my Enclosed NEO Trailer and will work with any Hitch on the Market. Plus it can't rock up and down on the end like Hitch mounted ones do.

ROCKSTAR™ Full Width Tow Flap Customer Review After trying several different hitch mounted mud flaps, I found these online. All I can say is WOW. Easy installation and they do a great job protecting my boat. Even if I'm not towing, I like to keep them on since they look so good on the truck!

ROCKSTAR™ Full Width Tow Flap Customer Review The Rockstar tow flap is a fiberglass saver! We throw the tow flap on every time we are moving our boats so the tires don't kick any rocks up at the bow of the bow. Install was super easy. I love that we can remove the flap when we don't need it but quickly (within seconds) reinstall the flap with the spring clips. The flap offers tons of protection and it looks great!

Review by: Gerry M. - ME   star star star star star

shipping was fast. install was simple, but, instructs were a little odd. Photos always look at photos never read instructions. Over all really happy with this. Cuts the splash up onto trailer by 75% will never stop all but helps alot.

This is the third Item I have ordered from you and I am very happy with all three. Two before rear bumper and one hitch mounted full length mud flaps. one for each of my trucks. I like the before bumper more, but the hitch mount allows for other trucks to use while using my trailers.

ROCKSTAR™ Full Width Tow Flap Customer Review Spectacular product!!! Very easy to assemble and install, no more that 40mins and it's ready to go! After the trailer was attached to my F-150, the tow flap was about 3-4 inches off the pavement, perfect! Drove about 200miles, no issues. Love the protection that it provide against small rocks, gravel, and such for the trailer.

These under bumper mount tow flaps are great. They are much easier to put on/off than hitch mounted tow flaps. They are well constructed and appear that they will have a long service life.

Review by: Kent R. - TX   star star star star star

I am very happy with these tow flaps. I had an issue with them and it was resolved immediately. This company stands behind its products. I would not hesitate to recommend ACI for any of their products and will absolutely be using them again in the future.

Review by: Mike M. - PA   star star star star

The full tow flap seems to work well for keeping stones from chipping my boat. It's well made but didn't quite fit the brackets after mounting them on the truck. I had to bend the aluminum plates a little bit to fit over the brackets. But overall I recommend it.
