    Nice setup to mount a new axle: The products looked to be of nice quality. They are made in China but what isn’t these days. Only the springs are painted so you can weld everything as needed with ease. The box didn’t come with all the components, however the seller was quick to ship the missing parts. Open your box when it arrives and not when you plan to work on it. I lost about 2 weeks waiting on the missing parts. Overall it worked great upgrading my enclosed single axle trailer I carry tools in. I constantly overloaded it and now I won’t have to worry. Best value for the components I needed.

    Some components unfinished: I haven’t loaded the trailer yet, so not sure how they’ll compare to the OE springs that came on my dump trailer, however they seem to be an even comparison. The kit came with the bolts, shackles, etc needed which was nice. My only complaint is that most of the hardware apart from the springs themselves were just raw steel. Without some kind of protective finish they will rust away in no time so the project had several hours added after priming and enamel coating the hardware to prolong the expected life (especially in the Northeast US where I am). For the price I’m happy to prime and paint, just wish I knew ahead of time that was required. UPDATE: I’ve used the trailer a few times, springs seem to carry the load as well as the original springs did. No complaints, this was a useful and convenient parts pack to replace a broken leaf spring.
