Z06Vette.com - Corvette Z06 Forum - Changing Gears- Do I need an Hardened output shaft?

slamar1 · 10-20-2003, 08:42 AM

Good morning guys!

I am going with 3.90 gears. Do I need to do the hardened output shaft?

Current Mods: Halltech tunnel ram, Borla Stingers.

Future Mods: Headers with cats for sure, possibly a mild cam/or 1.85 lifters with some aftermarket heads.

Thanks for your help

If you can afford it...then YES from what I've seen/heard.

I agree with Wingnut!!

I had cartek put 3.90 gears in and said what the heck...might as well do the hardened output shaft at the same time.

Do Z06's have a HOS from the factory with the stock rear-end?

I have the hardened drive shafts because I bought the getrag unit where it had them already.

If you don't drag race with drag radials, I not 100% convinced you need them. Its not a bad idea..but not mandatory (unless drag race with drag radials)

The funny thing is these "hardened output shafts" are actually more flexible than stock so they give more before snapping..

Just an fyi..and they certainly are something to put in if your not sure if your going to hit the drag strip..

Might as well package the unit the best you can.

Especially if money is no object.

What is it? An extra 2 hundred? What the hell..

Not necessary though...

Do it! I am stock, and I snapped mine last night. I run BFG gforce 315-30/18's... It hooked on a 5000 rpm launch, snapped when I shifted into 2nd.

Damn those "freeway on ramps"...

Thanks for the info guys. Better to be safe than sorry. Sorry to hear about your broken car.

I bet the crowd liked it though!

I don't have the shaft and I have about 200 passes on the car with ET STREETS AND NUMEROUS 1.6 60FT'S...... But eventually ill get gears with the shaft.
