I am also very surprised Dodge doesn't through in the tow hooks on our trucks. I have a '01 3500 that I added the factory tow hooks to. I believe I paid $150 w/tax for them. The price is quite steep, but they're extremely beefy. Part of the cost is for the bracket that mounts to the frame. When I bought these hooks I was very surprised how heavy the box was... there's a lot of hardware that makes up the kit. I actually think that this was about the only thing I've every bought for a dealer that was probably reasonably priced for what I got. This of course is my opinion.
When you install the factory hooks, you will either have to remove or make holes in your air dam (assuming you have one). The outlines for the holes are molded into the plastic and I just used a dremel tool to cut out the openings, rough sand, and then followed it up with some regular sand paper. You literally can't tell it didn't com standard.
In case you haven't seen, the tow hooks look like a much beefier version of the tow hooks that come on Chevy's (atleast the old body style like my brother-in-laws '97 Tahoe). If you've ever seen the Ram 1500's with the off-road package they look exactly like that with the exception of they're much thicker.
