Factory Mopar tow hooks for the CRD work quite well:

My only caution would be not to "jerk" with them. The're mounted firmly for a factory component, but if you treat them like a 3/4" shackle tab, you'll rip a hole in the lateral connection that bolts into your steel crossmember (i.e. the steel "bumper" under the plastic).
Lots of folks have used hitch receivers as shackles and simply through-drilled them and mounted them to the two existing holes in the front of the frame that the tow hooks use.
