Great advice...The fixed lower control arms that come with inexpensive lifts are junk in general because the only place they can flex as the suspension moves is in the bushings themselves. Best case scenario they eat bushings fast, worse case, if used off road on more hardcore trails, they can rip the ca mounts off your frame and/or axles. Do yourself a favor and get some adjustables with johnny joints or duroflex joints (Metalcloak).
Completely disagree....pucks on 4" lifted springs do nothing but introduce the possibility of coil bind and can leave you with a terrible ride. I would much rather have a 1" body lift (in fact I do). It is barely noticeable, opens the door for a tummy tuck, and a higher gas tank skid, and when combined with a mml, gives you an extra 1" of clearance under the oil pan.
