Well the gears are done!
Just an fyi, the pinion bearings are indeed different on the 09 and newer 10 bolt and also the fill is not on the passenger side of the case, but on the rear cover itself. Still holds 3 qt's, and all else seems the same.

Used a .036" shim on the pinion and got the backlash @ .007". The gears do make a little noise, which I expected, they were 120.00...lol, hell I've paid almost 200 for richmonds that made noise before.

The truck drives about 100,023 times better with the converter than with the 3.23's and feels like it may have picked up a good bit, I only have about 20 miles on it so I'll break it in a while longer, change the lube and punch the **** out of it

 

NICE!! I knew you would like those gears!

 

Yup, mine felt 100,023 times better too

 

Glad you got them in.

 

I have put some miles on and got in it from a dig today....it actually hooks better than with the 3.23's and pulls way stronger, the top of third pulls very good for the baby v8. I did set my speed limiter back to 105 to ensure that i won't test my luck with the driveshaft. Pulled great to 105, has a vibration at about 80 for just a sec. then smooths back out.....itdid that with the 3.23's too but it occured at a higher speed like....115 or so. I love the gears!!!

 

Mine felt good on the street. Then I went to the track and learned otherwise.

 

Here are a few pics of the pattern and the difference in the pinion bearing on the inner side.

 

Sweet! Glad your happy.

Did ya install yourself?

 

Yes I did, wasn't bad at all, getting the pinion yoke off was the hardest part...lol

 

I am considering a set of gears for my 2011 Tahoe. Any suggestions on a vendor?
