I was wondering if there are any other options on rear ends besides the 12bolts/ 9inches. I want to get a stronger rear end but I see that these rearends are around 2 grand. WAy to much for me to spend at this point. If I break my 10 bolt, would there be anything else I could look into that would be strong? Possibly even a swap from a different vehicle?

 

There is a way to fab up a 8.8 Ford rear, but you're prolly better off with a 12 bolt.

 

Not easially. I've seen a few 8.8" Ford rear ends swapped in; but they require a fair amount of fabrication, and if you don't know what you're doing nor have the tools, then it's not a easy swap. Whereas the 12-Bolts or the 9" by Moser are pretty much straight bolt-ins (Minus a custom Driveshaft if required)

 

You can strengthen your 10-bolt, too.

My father in law got the 12-bolt for his '70 Buick from a you-pull junkyard for $200. It came off a Chevelle.

You could do that, but you'd need to buy axles and axle housings to fit your F-body, and possibly some other stuff too. Someone who knows more about rear axles might be able to elaborate.

 

Yea, the big problem with swapping in any rear-end in our cars is the Torque Arm mount; no other rear axles have that. That's the good part about the Moser/Strange setups is that they custom cast the housings with the mounts in them; otherwise something has to be custom fabbed up to mount the T/A as well as all the spring perches, shock mounts, and brake mounts.

There's another option. Look on the page for the Strange S60 Dana Rear End. It's about the same cost as the rest of 'em, but you probably won't break it, hehe.

 

What can I do if I go this route? What makes the 10 bolt weak? I see different diff covers but they don't seem like they would do anything.

 

What makes it weak is the 7.5" ring gear which makes for smaller gear teeth. The smaller gear teeth are what makes the axle very weak in comparison to the replacement ones listed.

 

The rear from a third gen Fbody will bolt right in.
It is 2 inches shorter on each side so you will need new wheels with different back spacing.
If you can find an L98 car with rear discs you won,t have to go with drums.
The corporate 10 bolt is an 8.5 which while not as strong as a 12 bolt is still alot stronger than the 7.5 10 bolt in our cars.
There is a post on LS1tech of a 94 with this swap. I think the rear he used was from an 84.

I am trying to get the rear end with discs from my old IROC 350.

 

all 82-92 camaros and firebirds have the same 7.5 or 7 5/8 rear ends as ours except for some firebirds had a 9 bolt which I hear is a little stronger but parts are really expensive for it. just dont want you to spend money on a rearend out of one of those cars and have the same junk that you already got. 8.5" rearends are in monte carlos, caprices, and cars like that but they wont fit with out mods. I got the same problem you do I've been through 3 10 bolts and have been lucky with the one in it now its a stock housing and axles with a posi from a 2000 trans am with richmond gears. I've pulled 1.7 60 foot times with it at the track and with my heads and cam I've pulled better than that I'm sure just haven't had it to the track. I should knock on wood but it doesnt make any noise or vibrations so far. good luck if you come across any other cheap stronger rearend let me know

 

I was wondering about that.
Especially the later years.
Didn,t the early 3rd gens come with a corporate 10 bolt? I thought some did.
Never really hear of them breaking like the 4th gens though, and yes I know they had less HP but they did have a decent amount of torque.
Oh well, it was wishful thinkin I guess.

 

I dont think even the 350's had over 250 ft. lb. of torque high 14 second cars if they ran really good and barely enough power to turn the tires over. I know of several camaros that body style I've been under and all of them are the wimpy 7.5, except I've seen 2 of the 9 bolts, not sure what size the ring gear is though I think 8" but I dont know. I put 4:10s in the 91 z28 I had and it always did good then I pulled the gears out and put them in my 94 and a few months later shattered them. running 13.7's

 

You're kidding right? Try adding about 100 ft/lbs to that.

There was another rear that came on those cars; it was a Dana 44. I'm not sure which models they came on, but good luck finding one of those, hehe.

 

In 3rd gens??? uhm, I don't think so... That was the time of emissions choking everything; F-bodies didn't come with real HP numbers since the VERY early 70's, up to the 4th gens.

 

The L98 had 340 lbs/ft of torque stock, more than the LT1 stock. They did run out of air about 4.5K rpm though.
