Limitations of Axles
Monday, October 31, 2005 11:58 PM
I wasn't sure if I should post this in Performance or Transmission because it's part of the drivetrain but does anybody know the estimated power limitation of our stock axles. I'm wondering because I'll probably be running 15+ PSI on 9:1 compression by the end of January and I don't want to blow them suckers when I go to the track.

Basically, I just wanted to know the HP ratings on them.

Any type of help would be appreciated.

ive heard for my engine[2.4] that it is somewhere near the limits of the rods, so say about 280whp, but im not positive on that....dont have a clue what it is for yours bud but would guess its about the same.....

I believe stock axles are all the same for 3rd gens

I doubt that anyone will be able to give you a definate answer. People have broken these axles on near stock motors. Others have probably been able to put down "alot" of power without having problems with the axles. It all depends on how you launch the car, tires, and wheel hop.




275hp & 306tq - 1999 2.2 ohv
13.2 @ 108 mph
-1996 2.4 liter + Turbo + Built motor + Torco + More boost = Lots o' Power

Mike Karas was able to break an axle when he was putting down around 280hp on Nitto 555R drag radials.

I asked a customer that come in here that owns a transmission shop. He told me that our axles are pretty "beefie" and should handle around 275 - 300hp. Now no I didn't tell him my car was pushing that much and when I asked him where he got that number from he said that the stock axles in the SRT-4 's aren't as beefie as ours and they can handle that so why shouldn't ours be able to. Now I don't know if thats true or not I'm just relaying info.

LOL that seems like a sad assumption to compare 2 different cars parts and describe them as "beefie" and no other term.

<---snapped an axle running nothing more than intake, both motor mounts, stage III clutch and flywheel.

In other words, I would in no way shape or form trust stock axles putting that much power--there's no way to tell if you have a metal defect in them--like mine had.

SO, i'd suggest saving up the $600 or so, and getting the stronger ones that are warranted up to 300hp.

Killa , I know its a bad comparo but thats what an expert??? told me so hey what can I tell you.

Keeper was that a 7000 rpm nutral drop or what dude? But I guess anythings possible.

Good Luck Killa let us know how long they last and when they give out.

Don't worry, the org will be kept up to date on my performance modifications.

I'll be turboing by December and motor rebuild by end of January/Beginning of February (forged internals 9:1 compression). I think after that I'll keep the PSI reasonably lower and just save up for axles.

Also, being that I have an stock auto tranny, I can't launch at high RPMs anyways...so that's even more of a less likelyness I'll break them.

Thanks guys.

Like said before its all in how you drive/ launch. The stock axels are definately some the more strong stock axels in the car industry. I've seen people break diff gears and not hurt the axels before.
The main thing is to not have wheel hop, make sure you have all the poly bushings to stop it.

he wont listen to me , and race it tell it breaks

then replace them


axles break on shock loads , it isnt always a matter of HP

NJ you worry too much, just look at Hahn's car, still on stock axles and 400 whp. Our axles should be the last thing you save up money for.

Good luck for your turbo project !

look at DSS. the weakest ecotec axles they make are for 400HP.

last time i heard our axles are the same size as a vettes...that says a lot right there



I used to race cars, now I race myself.

Exactly, is is all about how you drive the car. Wheel hop is the biggest killer of axles.

oh and i forgot to mention for Adam even if you got a higher stall youd still be alright and probably much better off with higher HP with your autop then a 5 spd cause as im sure you know autos are fluid drive and have some kinda slip no matter what unlike a 5 spd which is almost a direct mechanical lock up so id say running with your auto youd be alright with any amount you plan on running on the street

I just saw my buddy's 05 SRT-4 (which puts down 415 whp on 15 psi + 75 shot direct-port injection) launching on stock axles, with DRAG RADIALS. I'd say the axles are just fine.

When it comes to the J-body... there is a point, race them until you break them. However I hate to be left without transportation, which is why I purchased Adler's DSS Level 2 axles... that were upgraded beyond the specs of Level 2.

No, actually, it was a 2.5k dump....you can't really feather a stage III clutch...

But, considering my bro works as a QC guy for a aerospace metal finishing shop, he spotted a major cooling defect sight were it snapped.

While they may be stronger than most, it's the QC that worries me.

Alright guys, thanks for the advice.

Like said, I won't be revving high on a launch so that gives me more of a likeliness to not break them.

Well good luck which ever way you decide to go. And Keeper I was just messin with ya man.


But just the thought of a 7 grand neutral drop should make you cringe. imagine how much crap you'd actualy brake!!

I'd rather not think of that lol. Adam if you do get better axles and good tires on the car, remember. Brake boosting is your friend.

I know...but like I said, it's things like that which most people think about. Yes, the axles are comparatively strong, but the QC you have to wonder about. Why i'm saving the $600 for the ones guarenteed to 300hp. That way, if they break, i can at least have them covered under warantee, because the OEM one of mine that snapped, there'd be no way in hell--especially since i snapped it while racing.

Correction, they are DSS level 3 axles and hubs which have been upgraded.
