How tuff is the 10blt?

[Jaycenk]

I am looking at making more power in the future in my 98 Tahoe. I have been working on F-bodies for years and know those 10bolts are junk when you start making any power. How are these 10bolts in the Tahoe's? It is a 4 door 2wd model with 3.42's and LSD. I want to change the ratio a bit due to the fact I will be towing with it. So what ratio should I go with I was thinking 4.10 and having the trans built to hold the power and hold lock up on the highway for fuel eco. Let know what you think and any experiances with this. Thanks.

There are guys running 10s on built 10 bolts with slapper bars. They can be made strong ... you can do the same thing to your 10 bolt that you can to the car version. I wish I had a lil more money last time I was in the rear of mine, I would have went with cap studs, reinforced cover, welded tubes, etc.

I towed with 3.73s and it did fine. I have 3.90s in now. I wanted a lil more RPMs at 65, my OD was locking and unlocking going up the small hills here so ...

14 bolt is really common and a easy swap to do

Ok cool, so what kind of rpms were you seeing with the 3.73 V's the 3.90's or have you not towed on the 3.90's? I'm not going to be laying the wood to the rear just towing. I guess I need to do the math on the 4.10's and see where that would put me. Do you know of any write ups on building up the 10 bolt?

What is the 14 bolt out of? 3/4 ton?

 

[AtomicHoe094]

yea theres been a couple write up on it, but if you have a 4x4 get a 4x4 or if you have 2wd get a 2wd 14bolt you know. simply bolt right in

Not all the 14 bolt are on 3/4 ton. My SS has a 9.5" 14 bolt rear end. The ones in the 3/4 ton is the 10.5" 14 bolt.

Ok good to know guys, Thanks for the info.

I haven't towed with the 3.90s yet. I'm just doing the 500 mile fluid change now so ... I can get on it after this.

In my personal experiences... i find that the STOCK 10 bolts in the Hoes are F*CKIN GARBAGE lol. Im on my fourth one... probably my fault that i havnt upgraded yet.

AND

All i have in my truck is a Cold air intake, throttle body, exhaust, and superchips flashpaq.

lol the ones in the camaro's are garbage!!!! lol I have to upgrade that one first and thats not cheap. Gona be like 2500 bucks for 9inch or 12 bolt. Then I can work on the Hoe's rear :****:. I need to go to a junk yard and see what I can find. I might do that today.

im in the same damn boat as you, the 01 formulas rear will need replacing soon, but it only has 20,000miles on her. and my truck one is about to blow. maybe all those smokey burnouts dont help.. damnit!

The later 10 bolt Fbody rears sucked. I'm into second gens (70-81). Those are the 10 bolt 8.5s, they can be made strong. The 3rd gen and I think most 4th gens had the 7.something 10 bolts, those aren't worth upgrading.

The F cars and trucks had different 10 bolts though. The one in current trucks/suv is the 8.625" 10 bolt rear. There are upgrades to be had with it as well but a 14 bolt 9.5" would be a better diff to start with. .02

No doubt, a 14 bolt is better ... I think the swap to the 8.6 was 2000 when Chevy went to the coil spring rear.

The 10 bolt under the ass end of my 95 Tahoe is the 'same' as the one under the ass of my 80 Camaro, different widths, mounting pads, etc but the center housing seems to be exactly the same. Same ribbing even ...

Hmm thats wierd. MY 85' IrocZ Camaro had a 10 bolt 7.***" in there. Maybe in the third gen Camaros they went to the smaller diff.
