REAR END UPGRADES

[Mudsport96]

Right, and i agree with the weight issue. But depending on his plans i think being under 450hp a good posi would hold up. Now if was dropping a higher stall converter in it i would immediately go for the 9.5

I agree with the "good posi" and reckon there's more than one way to skin that cat. I am going the 9.5 route and have one sitting on my work bench.

Welcome to the forum Junior from Georgia Bulldog country. Location is everything, especially real estate. LKQ/Salvage/Used or junk yard, $$$ is all over the place, be careful.

The 9.5 is a great upgrade, but my opinion is the 8.5/8.6 is plenty strong for stock to mild power levels. The govloc (g80) is the weak link. Get a good quality posi unit... trutrac, auburn spring type etc, and you'll be fine. I know there is a significant weight difference, but i have a 8.5 in my nova making 400ish at the crank and a 2400 stall converter pushing through a all stock 8.5 with a mini spool and havent hurt it in 10 years track or 8000 street miles.

I never weighed the 8.6 vs the 9.5 but I did move both axles by myself many times and don't think there's more than a 100lb difference, probably much less.

Nice I didn't know you snagged one! Find us a sub $500 posi for it since truetracs are like $850

LKQ in Fort Myers had two of them and dropped the price to under $300 and couldn't resist. Yep, they still have one for $286.85. If I had the room I'd pick up a spare!

In this size, I figure the G80 will be plenty strong for my needs.

There's quite a few of them across America for less than $300.

That's a ridiculously good deal! I paid around $400-450 for 130k miles IIRC. $300 for a near bulletproof axle is so much cheaper and easier than getting a posi installed into a 10b.

If you get the chance weigh the 14b vs 10b just curious.

It is and I was thinking of weighing the axles but not sure how to do it at home. Our bathroom scale is glass! Definitely going to weigh the truck again on the CAT Scales afterwards.

Go to LKQOnline and look for 14-Bolt Saginaw 9.5" axles (RPO AXN) in RWD Escalades and Denalis (2007-2014), they all have 3.42 gears and G80. Just bought one for $289 plus tax but every area is different. LKQ even warrants it. So you have to tell them yours has a 9.5 with 3.42 gears.

We'll eventually install 3.73s in ours.

Did you search "14-Bolt Saginaw 9.5" at LKQOnline or did you search by vehicle? I can't come up with the axle you mentioned on their site. Thanks for the help finding how you searched and found it.


Edit: I spent a bit more time there and figured out how to search. You have to enter the vehicle to come up with results. Thanks for the pointer on LKQ Online.

Any inexpensive ones in your area?

I was initially searching 2006 Escalade 2wd's and there was only 1 in Texas that was about double the cost of yours. I tried searching 2005, but they don't have the AXN as a possible listing for 05, which is incorrect. I've seen one in an 05 also. Once I changed to 2007+ as you searched, I then found a few more and for the same lower price that you found. It's a bit perplexing that they have the earlier one priced significantly higher than the 07+, but it could just be a supply issue I suppose.

I'll probably keep up the search for an 05-06 one anyway, since I believe these were all 3.73 gear ratio, and that matches the gear ratio in my 04 Tahoe Z71 4wd so I won't have to re-gear to match the front diff.

Does the 2006 Escalade rear axle assembly bolt directly to the 2000 - 2006 Tahoe? ...per LKQ's website it does not. It seems as though you all have found success making the swap??

I can't see why not. I'd think they're both the same underneath--same mounting points. Only thing you'd need to worry about would be the gear ratio if you're 4wd.

 

[Carolina Brown]

Sorry I should have been more specific...is there a 14 bolt, 9.5" axle that will bolt right up to the 2000 - 2006 Tahoe? I that's whats on the Escalades or 2500's??

I will find out the answer to your question in the next few months. I have the axle, but it's not installed yet. There are 2 minor differences I've noticed already but haven't seen what it'll take to overcome them. The rear drop brake line is single on my Tahoe 10b and the drop brake line on the Escalade axle is dual lines. Additionally, the wheel speed sensors appear to be in a different location on the axle of the 14b vs the 10b. I'm hoping the wheel speed sensors will just plug in. The brake line I haven't sorted out yet. From looking at it, it appears everything else will be bolt it up and go. Time will tell.

I'm wrapping up a 6.0 engine swap and having a heck of a time getting the pcm tune sorted out here in CA. With our Gestapo smog **** bureaucrats and their silly regulations and heavy hand, everyone is running scared with making any computer modifications. There are some diesel tuners that have already been fined out of business here in CA. Good job bureaucRATS, putting people out of work. SMH....

Here are the two differences noted before.

 

[Mudsport96]

After seeing Lawrence Tolman run several low 11s and a 10 with his turbo 8.1 extended cab Silverado on a 8.6 with stock everything except a real posi instead of govloc ... i dont think i will ever need anything sturdier lol.

Did you figure out the brake lines? I have a 2006 suburban that I want to swap the AXN 9.5 into.

 

[afpj]

The two vs one rear break line I "think" has to do with stabilitrak vs not. Nothing to do with rear pumpkin size.
