i dont know how you are driving but your car is a 4x4 the only way you can "loose a bumper" is if you are going down drive ways straight and driving it like a normal stock car. and second there are plenty of kits out there that keep the stock ride feel along with stiffness/softness adjustments and can lower the car,

RULE #1: lower you car

looks like you missed this step...orange lips black lips what ever you do, if you dont lower your car it looks riced out. Just keep that in mind.
