I just did the AEV 2 inch lift on my 12 JK. You will need a floor jack at least two jack stands. A drill, sockets, breaker bar, torque wrench, patience and about 4-6 hours if your doing it by your self. If your over 50 you'll need three beers a hot shower, ibuprofen and Ben gay after your done. Other then that its pretty simple. If your doing 2.5 you'll want to get the alignment checked. You might have to center the steering wheel which is simple. You can google it. Even at 53 and all the aches and pains there's nothing like turning a wrench on your jeep. Good luck!
