Harbor Freight spring under axle conversion
Anyone ever do this and is it safe? Trying to lower my trailer for easier loading/unloading. Here is my "before": when relocating the axle though I had some issues with the center bolt and the ...

The axle will not be as strong while it is inverted, because in that configuration you lose compression strength on the top of the channel and that will allow more flex under load. Also, being open side up its a rust trap. One easy work around would be to weld a plate on to the open side of the channel, while will allow you to keep it right-side-down, and also allow for spring locating if you drill a hole in the middle.
I would be suspect on the hardware used. Chinese steel can vary dramatically because there is little supplier control. While those U-bolts would certainly be adequately sized if they were from a North American supplier, I wouldn't count on them holding up if they are chinese. Since the axle is now under-sprung, the U-bolts are now supporting the load, instead of just locating the axle. It looks like a light-weight trailer, so maybe it doesn't matter. But if it were my trailer, I'd be sure I bought the u-bolts from a trusted source.
