I put Gm 4.10 gears in my 10 bolt with solid pinion spacer and a cover that preloads the carrier. Drive it every day on Nitto DRs. I'm probably close to 500 RWHP with an M6. Sees the track a few times a year.

Anything breaks with enough abuse.

i have owned 3 fbodies all of which had / have 10 bolts now no they are not as strong at a 9 inch etc, But they are respectable if you do not drive like a dumby ie sticke tires 500 hp and 4000rpm clutch side steps. It is possible for them to live. now if you had 700 hp that would be a diffrent story but with that power level I think you should be fine . wit the t/a girdle.

I went the times below on a 10 bolt.... Killed it shortly after though!!!

You will definately kill it with a 6 spd. If it is your daily driver don't risk it... Even with all the strengthening in the world they will not take the abuse of a six speed

Just ran 3 low ll second passes Sunday all @ 128+mph. Baby launches though with hard shifts on et street radials. Absolutely no rear end noise. 3.73, TA support cover, welded tubes.

I wouldn't mind sticking with the ten bolt if I added moser axels, found a strong enough spool, and added support bars, but the cost to do it is too high to try. 9" will happen over the winter, then hopefully some real 60's will happen.

Interesting thread. I guess I'm lucky, lol. I'm not making nearly the power some of you are but so far so good. I have the TA cover and Amsoil. I launch at about 6k to get 1.7's on GY DR's. I know this won't last forever, but I really wanted to see some 11 second time slips. If it breaks, I won't even try to repair it, upgrade!

Not that I'm making any real serious power worth drooling over, 10 years and 85k its still good (knock on wood). I'm in Germany so I'm just waiting for the day it jumps ship on me.

I'm gonna give braces and girdle support cover a shot on mine until I crack the carrier-or-shear teeth-or-twist off an axle. THEN.....i'll rebuild it better than before, see how long that holds up. But honestly, I don't see me breaking anything else anytime soon with the braces and cover on while on D.D. duty. If it does break, I won't be surprised because I will know it was coming based on what I was doing at the time of disaster.

We will see.....

I managed to shear off a few carrier teeth with the stock 16" wheels, extra streety tires, stock 3.42 gears... hell I think all it had was a lid/loudmouth. I dumped the clutch with traction control still on, then dumped it again with it off and finished showing off (while trying to salvage the muscle car hype which was all but destroyed at the sound of traction control pulling the plug). The next morning the rear end was loud as hell, and stayed loud for another 60k miles until I put my S60 in.

I'd say that if I had of ever hooked up with good tires then it would have been over in a snap... no pun intended

Don't get me wrong- there are PLENTY of better rear ends out there and the 10 bolt is NO heavy weight. And i'm fully aware of it's inadequacies, which I intend to address as they arise instead of dropping $2k + on a rear end that's overkill for a daily driver. I know, why would I want to waste my money on a "bandaid" or my time repairing it for that matter? Just call me crazy! Only the general knows why they chose something only adequate for the vehicle in stock form and nothing beyond that. But everything has it's limit, the 10 bolt's is just too low. Time will tell, Hell I might just get it to withstand a couple of 11 second passes here and there- it's been done and it can be done again....on my ride.

My M6 makes 441HP N/A and 572 on spray with just 1 bottle gone through it..with 4.10's and a girdle and STREET ONLY tires lasted about 6 months WITHOUT EVER going to the track..before it twisted the splines on the axles and wore out the posi unit to where it was making knocking noises taking turnes and starting to spin just 1 tire all the time. Now has a 9" with 4.11's and a spool.

I've got a few parts from my old rear end that I need to sell... like my mac cover, steel driveshaft, and axles... since I'm no longer going to need them I doubt anyone would want my clunky carrier or loud 4.10 gears though.

You can build a 10 bolt to accept everything except serious power (over 500 WHP), but it cost so much that you are much better off spending a little extra and buying a Strange 12 or Moser 9 rear axle. These set ups bolt right in, and better yet, weigh considerably less than the OE axle and brake sets.

"Weight considerably less than OE 10 bolt"?????????? I can't help but doubt that statement is true. How could that be?

I've been bracket racing mine since 2001 and have broken 2 posi's. Eaton paid so not too bad and cheaper than $2-3k for an aftermarket rear.
I have a Auburn pro-moser axles-lpw girdle-richmond gears.
I launch at 1800.

You can get an assembled S60 with a spool and a billion HP driveshaft shipped for ~$2500. Maybe less. I've got just a hair more in mine (35 spline truetrac) and its pulling "daily driver commuter" duty right now. I know it's a big up-front cost, but you can stop worrying about how you're going to make it to work tomorrow if you want to hit the track tonight with slicks... or in theory, you could rev it and dump it all the way to wal-mart over and over and it won't so much as yawn. 1200hp limits on a 370rwhp car = extreme reliability.

I saved my $ for a long time and finally dropped the bones. If you're worried about the $ part of it then you've got to ask yourself: Are you planning on keeping this car? If you plan on keeping it, and you're talking about a ~$2500 investment that will make it bullet proof then go for it. After all... unless you purchased your car new you can't have a whole lot of money in it from the initial purchase... I purchased mine for $8500 back in 2005 with 60k miles. If you can't add the cost of your mods to your cost of the car and enjoy what's actually a $20k car (at this point for some... if not more)... then why even bother.

For some people, however, they plan on making a bolt-on car to taunt a few mustangs in their town, maybe hit the track a few times, and then sell it for something else... then it would be hard to justify the cost of a rear end in this economy. For those folks it might just be easier to replace what breaks when it breaks and sell the whole thing after they're done.

It's hard to find folks who are hard core into racing their fbody (and serious about keeping it) that haven't put an aftermarket rear in. You're eventually going to replace enough stuff, or build it up to the point where you could have put a 9" in it... That's just the unfortunate truth to our cars. We got decent trannys, great engines, but terrible rear ends.
