Ease of Installation
The directions on how to tell the right from the left is not very descriptive. If you look at the center connection you can quickly tell which goes on what side of the truck. Otherwise the installation was done in an hour.
Lighter gauge than I expected

Ease of Installation
Ordered these to replace a similar set that rusted off after exposure to several winters' worth of road treatments in Northern Virginia. Installation was very simple, three brackets on each side then mount up the bars to the brackets. Instructions were pretty clear and easy to follow. I do recommend laying the bracket pieces out and comparing them closely to instruction diagrams -- my front mounting brackets were mis-labeled for driver and passenger side (I have photos) which caused a moment of head-scratching before I realized what was going on. The brackets are all stamped with two letter codes for (DF, PF, DR, PR etc) so you supposedly know where to put them. Pictures did not lie though.

Once on, the bars look great. My only concern is how long they will last; I know I did not buy the top-of-the-line product, so expected them to be a bit lighter, but the wall thickness on these was quite a bit less than I had expected. If they perform like the ones I took off, I give them about 5 years before the rust gets them (unless I do a better job of washing my truck on a more regular basis...) Paint coat was scratch free and glossy. Packaging for shipping was very well done, each bar individually padded and the brackets compartmented in a way that ensured everything arrived without damage. Overall I am pretty satisfied based on the amount of money I spent. I wouldn't want to take them out four-wheeling in any serious off-road terrain, but they should work just fine for the suburban environment I drive in.

I received exactly what I ordered and was very pleased with the black oval nerf bars.I was not at all happy with the installation graphics and directions. With today's technology, a better installation picture and detailed directions can be provided.
