The diff drop kit makes your CVs more reliable. But it takes at least 1.5" of front ground clearance under the cross-member - this is an expected consequence, but still this is unfortunate. Also, my observation is that it makes the cross-member weaker. It could be designed better, but it would cost much more $$$. I use the kit and I think I am fine with it.
