I've heard the gears are fairly cheap ($300-$400) If you have the know how it wouldn't be a bad install. I however opened the rear up on my 03 Duramax and boy was I sorry. I didn't really know what I was doing and me and 2 of my college buddies tried to rebuild the rear end. 3 days later I was at a GM dealership with a $3k check for them to fix it.

The world according to Tim is as follows
in your 20's, you can do most anything
in your 30's, most jobs are not bad to do
in your 40's, you wonder why you decided to do it
in your 50's, you ask how much it costs.....

RPM TRANSMISSIONS can do an excellent job. you already have an 06 rear, just do an gear upgrade exchange with them. if you think this is a do it yourself project, you might want to price the tools you WILL need to do this job. you might be suprised. they do good work and will stand behind the job. good luck

The gear sets are not holding up, setup perfectly they start to whine very early leading to premature failure. This was happening about a year ago I believe, I found out as I to wanted to do 3.73's.
I would contact RPM to see if they used this ratio and ask if they had any problems just to confirm, I have not talked with them about that specific gearset when I talked with them in person at the LSX shootout.

Hey Tim,
Option for you: Order a built diff from RPM and have it shipped here. You drive over for a 2 day vacation and I install it in your car for free.
Another option: Fly me there.
Call me for other details.
