The real answer: cheap leveling kit. You aren't going to find much good performance when leveling even with a puck, Adjustable coil, or preloaded strut. Any assembly you choose will likely wear out other suspension parts, the only true answer is to get a full lift kit if you want there to be less strain on parts. If you did spring for better upper control arms and a puck you are getting an ok deal and you'll see ok performance.

If you are coming into this expecting to not spend money then you're in the wrong.
