Essentially, it levels the front AFTER YOU HAVE LIFTED THE REAR.
So - Is it something you should consider?
Did you, um, lift the rear?
Do you want to?
You'd also need to purchase the parts that lift the rear...
You would be installing a lift kit, raising the truck about 2.5".
Its a small lift, and would not make a big difference in handling or ride, so its pretty much a ground clearance improvement.
If your ground clearance is a problem, and another 2.5" would be worth it, sure, its a good idea.
They also have a 5" lift kit if 2.5" is too little for your clearance problem...albeit 5" is more of a significant center of gravity change....and being released along the lines of New Windows Updates an other similar schedules...
So - does this work for you?
No wrong answer, only you know what you need.
