2010 Camaro Rear End, strong? weak??

So whats the deal with the stock Camaro SS rear end? I've heard it can handle 700 Hp easily from some and others are saying there breaking left and right?? Whats the truth and what exactly is breaking on the rear end? I'm looking to make my car a 650 HP everyday driver and don't want to be spitting rear ends out all the time. Thanks.

There was a limited problem with the output shafts in a select number of manual v8 trannys. It has been diagnosed and is being resolved. The tranny is tremec and is proven in vettes, vipers, stangs and everything else. All of those cars use some version of tremec and the ss didn't get a bad version just some of them got a few bad parts. It was not widespread. I think your safe in the 600 to 700 hp range.

There has been a few people breaking the axle shafts, not the inner or outer stubs but the shaft itself.
The inner and outer stubs are huge in comparison to the GTO IRS. It's the axle shafts that are the weak link.

I ran my car pretty hard at the track last night for about 8 - 10 runs and it felt solid. I have the LPE 570hp package putting 520hp to the wheels. I also have 2200 miles on the car. I think you are safe as well.

Have you seen pictures of these broken shafts? The only pictures I have seen were on ls1tech and it was actually the inner ball race of the cv joint that broke, not the shaft. From others descriptions, it is hard to be sure what is actually failing. Either way, I'm not sure if these are defective parts or if they are simply a marginally sized cv joint. Based on some in the 11's on stock units, as well as the failure mode (several not even at full power) of the shafts/cv joints, I believe the failed ones were probably just defective, similar to the tailshaft issue.

Look at my post about the axle half shafts.

http://www.camaro5.com/forums/showthread.php?t=97387

I ran it about 10 passes at the track without issues. I did one small burn-out and power shift and broke the passenger side. It didn't break into two pieces or at the shaft itself.
BTW - Car is 100% stock.

The rear end is strong and only needs upgraded axles for your intended power goal. The stock rear center section has lived fine in 9 second cars.

I would disagree,first there has only been a handfull of 9 second passes and most of the time those are types of cars that dont get many miles on them,in other words the next pass could be the rears last.Most cars that run great times use a smaller rim than the 20 inch stock wheel therefore giving the rear a big cusion since it has alot more sidewall to soften the hit. We have seen many,many failures with the stock rear and aftermarket gears due to the size of the gear and the weight of the camaro. You can have a lot less power than the 9 second guys and granade your rear with the much smaller sidewall that your 20s have.

I toasted the clutches in my rear with only about 500rwhp. A nine inch is being installed to replace it.

Keyword to alot of those failures being aftermarket gears thus not being a stock center section. If I were you I would disagree with me too because otherwise you might not make as much money. Until recently there was not even an option for a different rear end and many many have been doing multiple passes on the stock center section with zero failures on slicks. I think cutting 1.5 60ft times with 1000hp is alot more abuse on the rear end than 20" wheels.

All I can tell you is that my rear went. Only 500RWHP also Janetty racing has a "patch" available to fix what he sees is the weakness. If you start doing 1 wheel burn outs or feel you are not getting the power you should, check the rear it probably needs working on.

OK i got tired of reading those after about the 8th one and none had a rear end failure other than axles which we all know are weak. Some of those threads had nothing to do with anyone breaking anything on the car. Most were axles or transmission failures. This rear end is alot stronger than people give it credit for. I am coming from a 4th gen F body and this rear end is 10x stronger than that POS s-10 rear end.

X2 - Whats your definition of breaking? I've got an automatic tuned to shift quick and hard (compared to stock) and doubt I'll break axles however the posi went after a couple dozen passes with stock gears and 315 DR's. You dont have the shock load on the components with the automatic (until someone develops a trany brake) but you are putting torque to the same components. Without the shock load we have found the component (posi) that can not handle the torque. I had a conversation with someone who has been in the 9's on all stock coponents (automatic)from the drivrshaft back on slicks who has not had an issue with the posi because they are being very carefull not to. The main advice he gave was to get the wheel speed up in the burnout box to minimize the stresses as thats where your likely to fry the posi.

IMO If you bought the stick you most likely will need to beaf everything up if you (Drag) race seriously because you will eventually break. With the automatic the posi will eventually bite you.

31,191 active camaro5 members - members that run ther card reallllly hard 1000- people that run car at track and semi hard -3000- people that never run at track that do burnouts, shift hard, and sometimes have no real idea how to drive, shift or prepare car for no wheelhop...wheelhop is usually a recipe for driveline catastrophe ,the other ramainder of camaro5 members- 27,191...so how many members are having driveline issues ..lets say 300..thats a high # but still represents less than 1%..i,m sure a part of that # could also be related to driver error, not learning proper techniques or staying in throttle thru wheelhop..so answer to question is - is driveline weak.-no..can you break driveline parts -sure..can you do things to help not break driveline parts- definetly..it also has been shown that lowering car can increase chance of breaking axles, due to pitch of axle spline...but if you mod car keeping the premise of what a stock driveline can perform , and drive it like you stole it ..you most likely would be ok...but don,t build a 1000hp car like speedster and expect it to be able to perform on stock driveline ..imo

520rwhp? That's a lightweight. Almost everyone with an SS get's that with minor upgrades.
Based on all the posts on C5, I think most people need to start upgrading once they get into the 600+rwhp ranges.
Clutches, going and rear ends busting up all over the place.
But, if you're getting over 600rwhp. you probably don't mind the upgrades to utilize the power safely. I know I"m not going to mind it when mine is 700rwhp.

Blown Rear End

I blew my rear end two weeks ago at the track. I was doing my third run, going against another 2010 SS. I got the rpms up to about 2800-3000. When I let the clutch go I heard a loud bang. Well to make a long story short, when chevy opened up the rear diff the tech noted " found spider gear's shattered and severe metal contamination" The dealer replaced the rear under the warranty. I was lucky this time, but I'm beefing up the rear this spring.
