1. My driver rear bracket was fabricated crooked and I had to put in my vise to bent it and then hammer the backet into place. It was coming in contact with another stud bolt. (Other bracket slid in just fine)2. They do not offer very much step assistance. They do not have a very low drop on them and mind as well just jump into the cab without them. With that being said, they will be really good at getting the back of my pant legs muddy.

The packaging was a joke. One of the bars was busted through the box. Passenger side bar had to be shimmed at the mounts because the door would hit it. Obviously not fabricated properly. On top of all that, they started to show signs of rust along the top tube seam after about a year. I just started the warranty procedure. I will share how that goes.

Best bars I've ever owned. They are very sturdy and don't flop or shake. Metal seems a bit on the thin side so don't dent them.

Received with no mounting kit. Box was taped together loosely so I’m sure it fell out. Not sure how they expect me to install without the kit

Installed this step bar in less than 30 mins. Bolts right in to existing factory bolts. Very solid. The bends on the corners make it look like it came from factory.

I ordered these for my husband. He said they were easy to put on! He loves the way they look and the wide step pads.
