I was surprised that the 1750 spring flattened out and inverted somewhat. Boat and trailer maybe 2500 pounds. This is the downhill spring, so maybe 1500 lbs load. Tire nearly rubbing fender. I'll likely upgrade to 2500 per spring.

Package came fast. The springs fit like they should have. The hardware was good too. The only thing I may suggest is painting the springs and hardware again. There was a few spots on the springs that was bare metal and I will be using on a boat trailer in saltwater applications. Definitely would suggest this kit.

Although it was a great price and a great deal it did not come with the u-bolts like you described it would so I had to go buy new you boats so I can install all the stuff that I already uninstalled and tossed out I did not keep the old you bolts because I figured it said it was coming with new you bolts but did not other than that the product was great
