Rubber bed mat protection and appearance mod
The first mod I make for every truck is a bed mat, and with my new truck with a spray-on liner I knew I needed something durable but looks good too. This rubber mat fits super nicely even with a spray-on liner and prevents tools and items in the bed from sliding around as I drive around. It also gives a little more protection for the spray-on liner which is super nice. The raised spots on the underside allow proper water drainage and does not stick up too much so not a tripping hazard if you get in and out of your bed a lot. Super happy with this bed mat.

Great Bang for the Buck!
Looks great and was easy to install. I spent more time looking for my 10mm deep socket than I did putting it in. Maybe top 30 minutes…that’s all. American Trucks has never disappointed and this is another example. Great purchase on a budget. Thank you!

The step was perfect. Install was fast and easy. It works like a champ. The step only sticks out slightly beyond the bump which prevents you from running into it. Perfect height for stepping up on to the tail gate. Love it!

Great Purchase!
The Tailgate Assist was the perfect addition to my Truck. Prior to this purchase the tailgate would slam down and has almost hit people and my kids. Now, I have no worries of this happening because of the smooth lowering of my tailgate! It fit perfectly and does not alter the lowering of the tailgate at all. Great purchase if you have this similar issue!

Tailgate assist
Product arrived as expected. I was able to install the tailgate assist in a very short period of time, just followed the instructions. I works great and makes opening the tailgate a lot easier. It was a high quality product at a reasonable price. Highly recommend the item.
