Why would you run two shocks? You shouldn't need them at all. As for lift, look at AEV, currie, and teraflex 2.5" lift kits. All have what you need to run 35" tires with no issue. Above 3" and you're going to need to replace driveshafts and such after a period of wheeling or even driving. Also you will need exhaust spacers for your application.
