Rock Krawler had a rough start when they 1st came out on the market. As I recall there where some issue with the joints and a few other things. The company was sold and the new folks seem to be turning things around. As for 5.5" of lift.. I know that several folks who have the re 5.5 kit have switched over to 4.5 springs as they felt the 5.5's where too tall. And last yes a 1400 on a 20 ramp is a good score.
