Just FYI

Wow, it's the middle of April and the June issue is out already? Since I recently ordered a 9", I'll have to check it out.

Yep, don't know what's currently "on the newsstands" but us subscribers definitely have the June 2008 issue of Car Craft, already in hand.

This article makes great reading for anyone considering an axle "upgrade".

Yeah, it is in fact out on newsstands. I skimmed through it.....makes me even happier I'll be getting a 9" that weighs the same as a 10 bolt.

No gains in unsprung weight for me.

You mean compared to a 12 bolt, right?

Our stock 10 bolts, have got to be at least 30 - 40 pounds lighter than any 9" inch.

Nope. That's not the case for a fabricated 9" rear.

Wish I could see, although I already have a 9" and feel pretty confident about it. My Cummins has a Dana 60 up front

Who makes this fabbed rear that you are talking about? Is it the one from Midwest Chassis?

Here is the Midwest. If you go with the aluminum gear case it will be lighter than the 10 bolt.

There is even a chromeoly torque arm and tunnel brace that are not shown in the pics. Looks very similar to the M9. But a lot cheaper.
