Specs came from NAPA coil spring book. The book lists the weight load of the spring (the weight on the front end of the truck), the spring rate - which means after it's installed in the truck with the full weight of the truck on it - how much weight is required to compress the spring 1". The free height of the spring ( meaning how tall is the spring right out of the box), the load height of the spring ( how tall is the compressed spring with the truck weight on it), and the coil diameter etc. I gave all this info in detail to "Weeds" in a previous post. Check out the "Search" option for more details.
