If you look at the AEV bumper in relation to the grill you'll see it does ride higher than stock and most aftermarket bumpers. The full width ends subtly sweep up to nearly meet the fenders, so approach angle is still as good as most stubbies.
...and to answer your previous question: The D-rings shown in the pic are mounted in the locations provided on the AEV bumper, no custom work needed.
...and back to crashes: AEV's front bumper is the only bumper to pass D/C front end collision testing, which is why it is allowed to be a standard part on the COD MW3 Edition JKs.
