I'm giving these 5 stars, but there is a problem with them. You need to add an extra washer inside the rubber spring since the metal insert is not actually attached. Other than that though, they work just as well as the $300 timbrens and made a huge difference in load stability. I will attach a photo. The bottom picture shows the truck without the springs with about 650lbs in the bed (atv) and 650lbs of tongue weight from my trailer. The top picture is off the truck with 1500lbs in the bed after adding the helper springs. You can see there is a significant difference in squat, and there is also a huge difference in how well the truck handles the load. These were worth every penny.
