Why are these shocks so cheap?

No, you have it all wrong. They are VERY VERY VERY VERY VERY VERY CHEAP. Don't waste your hard earned money on those turds.
 
They look nice, but they are just china made crap. They will fail you much much sooner then a nice pair of stock or works shocks. They will preform like crap too.
 
Dont get me wrong. I wasn't gonna even think about getting them cuz they were so cheap! I was just curious. I wonder how many people they scam into buying them.
