ALL packaged in a heavy duty box with separate boxes, foam padding and bubble wrapped small parts included. Well painted springs. All brackets were there, ready to weld into place. All nuts & bolts were there ready too, (to my great surprise). Only thing I would add is an instruction sheet to show the optimum spacing for the spring eye brackets. No big deal, it's all over the web. Even Alexa knew what I needed for bracket spacing !

Had a broken spring on a twenty foot trailer. This kit fit perfectly and came with everything needed to install. Seems heavy duty

I would have gave it a 4 all the way across the board. But it was missing 6 of the Locking nuts that you got to have. I had to go down and buy them at the local hardware store and they didn't have the cheap ones all they had was a nylon locking nuts and they were $2.25 each. Which is not a big deal. I didn't contact the company the complain about it. I just thought it was a bit of a hassle to do all that. I thought that quality control should have had a better grip on it. Another thing I didn't like is that it has nylon bushings where all the pin bolts go through and you know damn well that those nylon bushings are going to wear out in a fairly short time compared to what a brass bushing would. Next time I'll probably shop for an American-made product.

Buying the springs, mounts, hardware as an all in one kit is the BEST way to do it. This is a nice kit that fit perfectly. Tried to buy the parts cheaper by buying them as separate brands cheaper. Had to send the parts back for that method as they wouldn't fit properly. This kit is made to go together and is a guaranteed fit. Worth the cost because of how easy it went together. Less than 2 hours, all 4 springs, plus the center levelers. Awesome kit. Trailer rides so smooth under load and at 80mph. Had them in for a few months, hauled our racecars thousands of miles and the trailer rides so nice now. Absolutely love this kit. Would recommend it to anyone.

Product was used for a boat trailer. It is trailer parts! Within 1 month all the parts Rusted and the bolts that are to be used don't even fit. Its a disaster and the company since its 5 weeks ago will not take the merchandise back. I replaced another trailer with local parts and the same parts from a competitor, and there is NO rust and all the parts fit. There was no directions. Run away as fast as you can!!! They should be ashamed of themselves. they are selling cheap China Products that should be thrown away instead. Amazon , you should stop selling their stuff, and actually I am going to send an email to amazon also.
