Stengthening the 10 bolt?

[Nachius]

How can we make the stock rears less likely to fail under track conditions?

Auburn Posi instead of the Zexel?
What rear end cover?
Different Bolts?

Anything else short of changing the entire rear?

You could get a TA Cover that will make things alot stronger in the rear. It comes will grade 8 bolts and has bolt to keep the bearing covers from trying to go n e where. You could look into buying new axles.

There was an article in I think Chevy High Performance a couple months ago on how to bullet porf a chevy 10 bolt.

A T/A Cover with the additional stud kit will help alot....

Changing out the zexel to an auburn wouldnt hurt either....not a big fan of the zexel units.

I bought a rearend cover from summit racing with a girdle kit, and it was alot cheaper than the TA one. P/N is on my website. One of the mags did a total rebuild of a 7.5 rear, for like 7 or 8 hundred dollars and was rated to 400 or 450hp, but I cant find the article. If I find it Ill post it up.

True....The T/A cover was just an example....I would definately go with one from summit or another company that is cheaper....

You can do all you want to the rear itself but that will still not change the weakest part of the unit. The ring gear. 9 ou of 10 times when you have a rear failure it;s due to the breaking of the ring gear. A new posi, axles, cover, welding of the axle tubes etc etc will make it stronger but will still not do anything for the ring gear. Your less likely to break it the lower gear you stay with. People really have issues when they take a put a 3.73 or a 4.10 in place of the stock gear. thats a whole lot of teeth in a very small space.

Actually I was just thinking about this myself...

So really nothing other then an aftermarket cover? and major stuff like axles and such?

my friend has over 500 HP on his 10 bolt

Eaton Posi
deleted C-Clips
and some strong gears

does burns out all the time and hard *** lanches no bloplem but the axles...lol

I know people making even more then that on 1.4 60 foots on a stock rear. wanna know a secret? they are very very lucky. It all comes down to chance. you could throw everything that you have at it and never blow it. Or you could do like a friend of mine with a TA and launch a stock LS1 at an idle on street tires and have it go boom. YOu can do everything I listed above and aftermarket gears but it's still just a roll of the dice. you never know when it's gona blow. anytime your over 300HO on the stock rear or cutting less thena 1.8 for a 60" your in the danger zone. a lot of it comes down to luck and how the car was driven the first 500 miles of it's life.

I got sick of rebiulding the rear bearings and said screw it and got a 12 bolt. I new I would need one eventualy anyway so for me it was just preperation for the future. I know that a lot of people will never need something that strong. They would do pretty good with

. A better diff
. Cover with studs
. Aftermarket gears
. C-clip elim's
. Welded Axle tubes
. Better axles


and walk away with a stronger rear that "should hold up a lot better. But still one good speed mod is a larger gear. and thats the week spot. Like I said when you through a 3.73 or 4.10 at it your putting all the work you have done in the hands of the weekest point. Sure the rear itself would hold up a lot better. But the chances of breaking the teeth off from the ring gear is a lot higher.

But it is a step in the right direction unless you have some big plans for the car

With all that being said, IF gears are in fact the weakest link which brand aftermarket gears are the strongest?

I'm running GM 3.42s right now and plan to stick with the 3.42 ratio, but is another brand like richmond or strange a "stronger" gear even at the same ratio?

I think I may just do a cover w/ studs and instead of dropping a lot of money into strengthening the 10-bolt just put that towards a 12 bolt.

[HBHRacing]

richmonds I do not recomend. I have seen a lot of them break and they whill whine more then any other. I have heard a LOT of good things about the Motive gears. Thats why I have 4.11 motive gears in my 12 bolt [img]smile.gif[/img]

[Notoriousdom]

Nothing you can do to strenghten the weakest part it being the teeth of the pinion and ring gear. You are safe unless you get 4.10s and have a V8 on slicks. A stock LS1 M6 w/4.10s on slicks can easily shave the pinion teeth.

I doubt you will break the 3.42s. I've not heard of anyone breaking anything but 4.10s. Even with a V8 I would never worry about breaking 3.42s.

My dad works for GM, they are always fixing the v8 10 bolt axles due to breakage from the stock v8's racing. The axles should be strong enough to handle the v8 power but they are NOT.
