For 35's you'll definitely need a lift. A 2.5-3 will do. Anything over that MAY cause driveline failure and it will alter geometry. It will cost more to get it back in shape....track bars and control arms then alignment.
A 2.5 - 3,will be healthy. (If u plan on taking it offroad/disconnected)
There's many reputable brands out there. Rock krawler, teraflex, metalcloak, full traction. I will be running rubicon express 2.5 monotubes (tuned bilstein 5100's)
now for 35's....you may want to consider gusseting ur axle C's...it's very weak on our jk's. choosing tires....remember 10lbs is equivalent to 100lbs. The lighter the better. Good luck
Last, you will need to calibrate ur speedometer/shift points.... Aev procal is the answer.
