Ford 9 inch with 3.73 is there any downfall and how hard is it to mount

 

I have one. Just buy one from Moser. It bolts right in so its a piece of cake. The only downfall, if you can call it that, is that they rob a tad more power than a 10 bolt. But not having to worry about breaking the rear is worth it. I got mine with big ford ends on it and have a wilwood brake kit out back. It is a little over $600 I believe for the brakes. They may be able to make it though so you can use factory brakes.

Do you have the power to need a 9"? Or are you planning on real sticky tires at the track?

 

I have a Moser and the only downfall that I see is that it's so heavy. It bolts in just like the 10 bolt but if you run a 4" exhaust it'll have to be moved over slightly to clear the third member.

 

Lol, yes they are heavy. I had only ordered the housing and axle package from Moser and when I picked up the box I had sworn they sent me a complete axle
