beef up the 10 bolt? so spring tiem, I had plans to rebuitd the 10 bolt, it has a 3.73 right now i beleive. I was going to get 4.10 a stronger detroit locker, moser or strange axles, and a rear end cover. Is it worth the build?, I won't be over 450 hp for a while, unless i decide to spray it, the main reason is i can build it for a little over a grand. which is way cheaper than a 12-bolt or a 9 inch
here is mine, maybe you can get some ideas from it. My build was concentrated on strengthening up the housing, which is a main concern on these 7.5 rear ends. By making everything solid, the gears stay in perfect contact at all times, even under load, which substantially increases their strength. The other weak link is the carrier, in which i would suggest the Eaton

Good luck with whatever you decide!

I am taking a look at hazard2k's ideas and will go along with building up my 10 bolt. For ME as well, it is not feasible to spend for the 9" or 12 bolt now, car is not on the drag strip, not making serious power, A4, daily driver, and the rear is starting to make noises that could be a bearing.
So I might as well do it now, use it for a while and save fro the upgrade. Plus, after talking to some guys at the LSX shootout, making great power and hitting 10's and 11's on stock rears, it is possible.
I am looking at the auburn thoughfor the carrier, seems like they have a higher recommend the the Eaton, however, not buying it tomorrow, so I am still researching, listening and reading. 3.73's for sure, maybe new axles and I am leaning towards the solid spacer vice the crush, so it takes longer to set up, seems to be the prefered method I have read so far. (NO I did not take a poll!
)
Just my thoughts.......

I opted to spend a couple hundred bucks instead to make a 10 bolt be able to withstand the beating i put it through. And for the record, it has taken it pretty well.
BTW.. good luck with the donations.. I have not gotten any yet either!

hazard2k, U seem to have a good build there, so as of now im thinking of sticking with my 10-bolt cause its cheaper, and I plan on only hitting 400 hp with a good tune and a few more bolt-ons, so my 10-bolt should hold up for a while, i just don't want t build it, then have it bust a month later, cause it is a 6-spd, and I know they break way easier on 6-spds

There is always going to be people saying its a waste of time, and dont do it. But 500 bucks is a lot easier to find than 2400. Yes, a 10 bolt will never be as stong as a 9" or 12bolt, but if I can make the 10 bolt strong enough to last with the power i am making, why would i logically go bigger? To waste money? add weight? lose drivetrain efficency? Doesnt seem to add up IMO.
People need to understand there is more uses to a car than ONLY drag racing. For example, mine is being turned into a autocross car. There are plenty of people i know around town that enjoy just cruising on the streets with their 400hp cars. They also, would have no use for a 9" rear end, as they would not get traction anyways, unless they went with some M/T streets. but since they drive ALL the time, they dont have them, as they would be worn out every 2000 miles.
Depends on what you plan on doing with YOUR car, not what other people think you do with your car. If you go to the track every friday and drag it, then you would be better going with a guaranteed strong rear end (9" or 12bolt). If you do pretty much anything other than that, then a beefed up 10-bolt should suffice for the purpose.

How do I beef up my 10 bolt?
You don't.
It seems like too easy of an answer, but it holds true. The 10 bolt will always be limited by the fact that it is simply smaller than a 12 bolt, 9 inch, or Dana 60. Smaller = weaker.
Besides replacing the ring & pinion and bearings, adding aftermarket parts such as stronger axles only seems to be a waste of money. The minute you fix one thing, another will break. Rear end installs can be costly if you are not doing the labor yourself - it adds up quick. Don't be the guy who says he can't afford a 12 bolt, but has spent $1500 dumping money into his 10 bolt.

That's Your *** ! ! Your talkin outa your *** dude ! Obviously !
I beg to disagree. The factory 10-bolt is so ****** weak a Chevy Cavalier could make it whine & howl like a banshee with a lead-foot teenager at the wheel in less than a week!
