Body Armor 4x4 bed rack. Universal mid size truck. Part number TK-6126. Dimensions are on their website, but no weight. It roughly weighs ~75 lbs.
I took pictures of the package, parts, setup. Will create a folder and upload all images later. Just wanted to share a quick pic of a Nissan Frontier with this bed rack as I could not find any images online.
For the bed rack to mount with the utility track, you have to flip the utility track upside down. Unscrew the bolts, turn the utility track, rescrew in place. Then the rack will line up to the right height.
They provide the T nuts that slides into the tracks. The T nuts may be 1mm too tall, so you have to grind it a little bit. Some slid right into the tracks.
