Durability of gt350 half shafts?

[Andy13186]

I have the gr350 left axle in my a10 turbo car. Held up great so far. But I just turned it up a bit and broke 2 right side stock axles in just 1 day. So if the right side axle is the same strength as the gt350 then 1.4 60fts will kill them.

Footbrake or transbrake launch?

I’ts interesting to hear you guys that broke a dr side shaft broke them at the taper part outside of the boot. Mine broke something inside the boot. And it’s not some super high horsepower car it’s a damn eco. Then again it is a stick car and let it go about 4-4200 on a biasply and snap. It didn’t move but an inch or two.

so with that said who’s got the best deal on gt350 shafts I’m gonna need a dr side. I replaced the broke stock with another stock so the car would be functional but need upgrade come spring.

You would be wasting your money on the gt-350 axles especially with a stock ecoboost wanting to do 4000 rpm clutch drops. The gt-350 axles are a little bit stronger then the stock axles. Just get a good set of 800 hp axle shafts and never look back. I recommend G-force axles...

Many sets of GT350 axles are in 700-800HP cars with no issues. I doubt an Ecoboost will break them, although there might be 1 Ecoboost that could.

Were you dumping your clutch or slipping on the 4-4200 rpm launch when yours broke on the bias ply?

Somewhere between a slip and dump.

What’s the part number for the goto 350 axle? Is there any difference between the 350 and 350r?

Sheared mine on a 2-3 shift....
Broke inside the diff at the retaining ring

How long did you have those on and what kind of power are you making

had em on 2 months tops. 650 rwhp measured 2 weeks ago through hub dyno....

upgraded many components along the way, I guess I'm part of the select few that have broken gt350 half shafts.

I have cradle lockouts, diff inserts, vertical links, subframe alignment dowells, godspeed rear adjustable camber arms with camber near -1 degree.... MT82 with the steeda tri ax shifter and stiffer bushing as well as the whiteline trans bushing insert...

was running 305/35/18 mickey street ss tires. broke during 2-3 shift during some pulls and I wasnt exactly pushing it hard

No. None.

I'm about to throw mine on in a few days. I'm n/a so should last me a long time. Especially since most tracks are closing around the state.

Put a bias ply tire out back and that should help them live by absorbing shock on the launch.

Damn, wish I knew this before getting radials. I had always been told that radials for autos & bias for manuals.
