Mudflap Systems for Dually Trucks

Whenever you tow something your Dually, factory mud flaps are usually just not enough to catch all stones, rocks, road debris and obstacles that fly from the wheels.

They damage paint on the truck, trailer and towable, cause tiny dings and dents. In future, these imperfections may lead to rust and corrosion of the body of your Dually truck, damage your trailer, camper, boat or whatever is being towed. If that is something you are not willing to tolerate, Rock Tamers has got a solution for you!

Dually Rock Tamers: Adjustable Mud Flaps

Rock Tamers mud flaps are proudly selected by numerous American Dually owners, as these mud flaps are completely adjustable and easy to install when needed. Let us look into these mud flap systems more detailed.

By adjustable we mean a possibility to adjust height and width of the mud flap system once you install it on your Dually truck. Moreover, top-notch adjustment system allows changing the height of the mud flaps already on the truck. It is extremely important for those, who transport overweight cargo in the beds of their Dually pickup trucks.


When you load all the cargo into the pickup bed, look at the mud flaps and make sure they are not loo low. The heavier your cargo is, the lower the ride height is, which means changes to the truck height. Respectively, the mud flaps will also go lower, and you may want to fix this.

And vice versa, when you unload the cargo, the ride height of your truck increases. It means that the mud flap system will also go up and leave certain unprotected area. You will just need to go to your Dually truck and adjust the mud flap system height by making the mud flaps sit lower.

When nothing is towed and you use your Dually as a daily driver, you can easily remove the Rock Tamers mud flap system and keep it in the garage when it’s not in use. You will be able to install it back easily when you will need extra protection of your truck.

I've got a brand new Sierra (I picked it up this spring), so I took care of its protection, as in summer me and my family enjoy camping. Camping means having to tow a camper, and when you tow something, you get all the stones hitting your truck, which kinda sycks, especially if you have got a brand-new truck. So I bought a set of Rock Tamers, and I am happy with the purchase! Good protection, easy installation.
