Finally got around to installing these today on my son's truck. In the end, happy with the product and the look of the truck, did exactly what they were supposed to do and only took a couple of hours total. Only issues I had were they came with no hardware so I had to buy the center pin/bolt and nut separately and only one spring had the plastic bumpers, the other spring was missing both. Neither issue was a big deal but, would have been nice if at least the bolts were included. Adding a leaf requires a longer bolt so reusing the old ones isn't an option in many cases. I think 4 stars is fair, would have been a 5 otherwise. Still happy with the purchase. Would buy again.
