Follow the instructions? LOL A 2.5 lift is actually really easy, not too many parts and everything with that kit is simple bolt on if I remember correctly. Use real jackstands, don't trust your floorjack or whatever you're raising it with (unless you have access to a hoist). Even taking your time it shouldn't be more that 4-6 hours to complete and remember to set your steering wheel at the draglink before you drive it just to avoid throwing a code. I believe I see 35" on those tires so on stock wheels, you may need spacers to run those them. You can't usually turn all the way because it hits the either the frame or control arms with that size. You may also have to trim your flares if you go off road much.
