Yeah, looks like the available ratios changed along with the introduction of the 6 speed.

2009 ordering info now shows only 2 available axle ratios 3.08(standard) and 3.42 which is either available or standard on L76 models dependent on whether the truck is 2WD or 4WD.

 

Make sure you dont get an SSR or TBSS 14 bolt because the wheel pattern is different from the rest of the trucks.

 

Along with the track.

 

I'm going to get a 9.5" 14-bolt from a 2008 Escalade ESV. Want a GT5 rear but they are hard to find...the GU6 rears are much more prolific and affordable.

 

Did you call on the one i told you about?? it had the gt5 option listed.

Sure did, and received the VIN. Checked the VIN with the dealer...was informed that it was from a 5.3L Suburban and not a 9.5" 14-bolt rear. So I did a search for GU6 3.42 and found I could get one from a Cad Escalade ESV with only 20 miles on it for $1325 delivered to my door--that is a brand new rear. I'm continuing to look for a GT5 until I confirm with this salvage if that includes brakes/lines, panhard, etc.

ANYONE CONFIRMED IF THE PANHARD ROD IS A DIFFERENT SHAPE TO FIT AROUND THE DIFF COVER?

 

I just got some pictures. They are on my cell phone so I'll have to wait to get home to post them. The panhard bar is the same part number as the normal one's and it clears the diff just fine. At least 1/4" to 3/8" of clearance in there. LOL. The picture should show that.

 

Not sure what you broke back there, but why dont you save time and cost and put a good posi unit back there. Do a standard eaton with a 800lb kit in it. You will never break that. Its stronger than the true trak.

I've started another thread to chronicle my 9.5" 14-bolt rearend swap HERE.

I'll continue to post here with the 383/122HH upgrade stuff (pulley, cam, tuning, etc).

 

I can almost guarentee you that he will break the 10 bolt. I went through 2 Eatons and a Yukon Posi before I upgraded to the 14 bolt. I cracked the case on the Eaton. That was with a girdle as well. There is just too much flex in the housing. It is kind of like a 4l60/65/70e. In heavy applications with over 500rwhp, they are time bombs.
