I am torn between the Rock Krawler 2.5" Max Travel and the Metalcloak 2.5" Duroflex System. MC and RK both claim the most amount of misalignment capabilities. There is no question about RK being a great system. I have read that the MC system is a bit nicer on road than the RK. RK has a much better written warranty, but MC say that they are rewriting their warranty now (plus I've not read anything negative as far as standing behind their product). Pricing is about the same once you had the additional control arms to the RK. Both companies say that I don't have to change the driveshaft (surprises me with all that flex). Both systems are easily upgradeable to 3.5". Any advice/feedback would be appreciated.
