Aluminum Driveshaft, worth it?

javsvt · Jan 13, 2006

Thinking about aluminum driveshaft. What do you guys think? Worth it? I pretty much want to do bolt ons for now, funds are limited. Have on car now 4.10s, cai, chip, x pipe, flows, short shifter, throttle body/plenum, cc plates, and eibach prokit. If anyone has installed a alum. driveshaft, did you notice any difference? Thanx!

ive heard guys saying there are noticable differences, but nothing spectacular. like the engine revs faster, and theres no signs of drivetrain vibe with 4.10s.

Iv been thinking of one myself, it would help in the 1/4...maybe a tenth. Thats that much less weight your engine has to turn.

might aswell pick up a alum flywheel too

I have one and it is ok. If you are making alot of high end hp I wouldn't get an aluminum flywheel unless you really want it.

javsvt · Jan 13, 2006

How is my sig? Should have done it awhile ago. Flywheel, not yet. Im just looking for something quick and cheap to install. Just want to know if its worth it.

I know, it's not a 99-04, but I've got an Art Carr aluminum driveshaft in my '68 and while the SOTP measure didn't really feel any different, I dropped three-tenths of a second off my 1/4 ET, from 13.9 to 13.6 (dry) between the stock Granada driveshaft and the high tech A.C. aluminum unit.

+1 to the aluminum flywheel, too.

If you're just looking for a little extra weight loss and speed, and can afford it, hit it up. Just don't expect a huge SOTP boost.

I'm planning to get one along with the Fidanza. My buddy has this setup on his 00' SS and his stock tach can't keep up with the motor. Very noticable gain on the butt dyno!

i bought one back in late September, and its still sitting in box. I need some motivation here...

I've heard that after replace stocker with Aluminum shaft, you can take off dogbone without ill effect. is that true?

Justin03GT · Jan 14, 2006

as far as SOTP...not so much...but it is a lot lighter than the stocker and the car seems to rev freely now, like its not trying to move anymore...just flows well...i removed the dogbone when i did my gears, it had some vibration with the stock DS that went away with the aluminum..all in all its not a bad mod, saves weight and helps the car move more freely..

Yes get one...

Takes care of vibrations

Use the money for something else or save it for now. You will not notice anything. When you do install it add a driveshaft loop with it.

What is a driveshaft loop?

In case you driveshaft fails it won't kill you. The loop keeps the failed driveshaft in the tunnel and away from the ground.

stangGT97 · Jan 14, 2006

I would definitely get one. In fact, im planning on doing Al driveshaft/flywheel whenever I do my clutch

02GTdroptop · Jan 14, 2006

A driveshaft loop keeps the aluminum driveshaft from acting like a catapult if it snaps away from the transmission or the rearend at speed.

It happened at Laguna Seca a few months ago when I was there volunteering with my unit, pretty crazy. The driver lived, but it was fortuitous that he did. I didn't install a loop when I did my aluminum driveshaft until a few weeks later when I read about some kid dying in his '67 Camaro because it flipped over when his driveshaft cracked away from the transmission yoke.

But it's not common.

I've got an Aluminum drive shaft out of a Mark VIII in my Cat, but it's pretty much mandatory after the gear swap. These MN12 shafts are about a foot longer than the Mustang ones and the really start to get out of shape when you get them spinning.....which is likely the reason they saddled these cars with a 170km/hr speed limiter too.

How is that any different from a steel driveshaft car with a lot of power?

02GTdroptop · Jan 14, 2006

Aluminum bends about 6 times faster than steel my friend.

Try to bend a spoon made out of aluminum, then bend something made out of steel.

Which is harder?

Aluminum Driveshaft, worth it?
