I have not heard of this brand, but they look like auto parts store quality, which in my experience is not the move. I don't know though, maybe they're excellent. The price is right. If you can get a warranty on them and they aren't terrible, just keep changing them out nice and quick, you might be on to something. For sure the worst part of doing this job is the spring compressor part on the workbench.

I do have the Bilstein kit sitting on the shelf. I was going to get all new mounts, and all the hardware, to avoid the spring compressor and have a nice easy swap like you are saying. I believe I somehow ended up with $800 something in the shopping cart and decided I would try again later. The mounts, bump stops, price gouging bolts and various washers etc, adds up quickly.

So I do think you're onto something, if those shocks are any good, and you can warranty, it might be really nice. However they're probably just good enough for someone to pass inspection and bounce down the road.
