That is an axle chain for securing axles on heavy-duty trucks with air ride. I have used those for years, and they work very well for the purpose. The hook will definitely be large enough for pickup truck axles, but will not be the optimal set up. A standard tie down chain and j-hook will work much better for the purpose.

You really can't lose with anything from Whelen. I've tried many different brands over the years, and Whelen stuff seems to be the most reliable. There are other brands that can be brighter or cheaper, but they don't last. We use Whelen Justices on a bunch of our trucks, and they are very good bars for the price. We also have some Liberty IIs, which are more expensive, but a lot brighter.
