Will I need an alum. driveshaft w/ 4.10's?

[1hot5.0]

I sometimes hear that there is a bad vibration with 4.10's and an auto. The only way to correct this is with an aluminum driveshaft. Is this correct information or no?

pretty much

I got my 373's last month and had a vibration under wot,I got the A.driveshaft and it went away!So Id say yes.Im glad I did,Im getting 4.10's next week!

Some people said they are suprised I do not have vibrations with 4.10 gears....Stock driveshaft(til next week) and no probs...

Hmm, I'll have to see if I have problems or not. I'm definitly putting one on though. Thanks guys!

what exactly does an aluminum driveshaft do?? whats the difference?

i don't think the vibration is from 4.10's, it's from the gear swap in general. the driveshaft is spinning so much faster than before. the aluminum driveshaft is balanced better, weighs less, and since it weighs less has less rotational mass to deal with which equates to less drivetrain loss.

It has nothing to do with it being lighter,the factory DS had a balance problem!

i was stating the pros of having an aluminum DS

I didnt have any problems with the stock driveshaft 4.10's and a auto. I think its a hit or miss thing Id wait and see what happens.

Sorry im sorta stealin the thread a little bit, but would an aluminum driveshaft be worth getting anyways..?

vibration at 70 4 me... 4.10s an an auto

fox 5.0 an aluminum driveshaft is a must if you're increasing horsepower and of course torque is the main thing. my stock driveshaft had very little vibration after i put the 4:56's in my car, but after a couple trips to the track and some good hooking blam drive shaft was vibrating bad due to some nice twisting. put an aluminum one on and wham no vibration since and no probs. at the track either. the cost of getting a stock drriveshaft balanced plus new ujoints is to close to the cost of an aluminum one to not get one. I have heard of people using hose clamps to help balance a driveshaft but i wouldn't recommend it to much. lol

I see... thanks for the in depth detail... never really knew what the purpose was of one...

 

[bgjohnson]

yeah it's a very good idea for another couple reasons also. The added vibration in the D/S will actually hurt bearings(pinion and outputshaft)and can limit seal life, so it's definatley worth getting, everything is so much smoother.

 

[goldbomb79]

yea, it will also junk out the rear seal in the tranny and if youdon't notice it quick enough you'll lose tranny fluid and you know what'll happen then

Thanks for the replies everyone. I'm going to drop off my cat at the shop now. I am so excited!!! :bannana:

it's good your excited about gettin stuff done to your "cat", whats it gettin, like a performance nueturing, J/K man, just givin ya ****

i put 4:10's in my car like 6 months ago and i had the vibration everyone is talking about about 60 mph. they place near me wanted $75 to balance my stock drive shaft so i went ahead and paid $160 for the aluminum and im glad i did. i picked up almost .20 at the track. just my 2 cents.

Rotational mass has nothing to do with driveline loss. Absoutely no HP difference between alumn and steel drivelines. If it has less vibration, it's because it's balanced better. Steel driveshafts, balanced correctly, will run just as well.
