Frankly just because it's made in China doesn't make it garbage. So you can pretty much eat the whole china thing. Just saying. If you let china design something, then yes the quality is usually lower. But for companies that design their own products and get them produced in china with their specs, it doesn't mean oh god it's China it's crap.All these bracket/spring lifts do is jack the shocks up a little. No one makes a real 2" 'lift kit'.
The 4" from Catvos seems to be ideal from my vantage point. I wish the trailing were a little shorter, but otherwise, it seems to be a very good kit. Though it seems expensive, you have to remember that about half the cost is in axles.
Companies like SuperATV can do it cheaper because they make it in China and the axles are also Chinese made.
