I noticed on the parts truck I took the tranny from was a v6 model and had a aluminum drive shaft that seemed half the weight of mine would it hold up to the power?

Mine has held up so far but they will break sooner or later.With the
new 392 I choose to go with a steel driveshaft....

High speed and 4.56 gears has broken all the aluminum driveshafts I've ever read about. Not really power related, just critical rotation speed.

Ok fine I will leave it on the truck just a good weight reduction idea thats not such a good idea for my truck

You can get a custom lightweight aluminum driveshaft thats designed for abuse... they're usually around $500

Had my driveshaft/u-joints built in '04, rated to 800hp. Yes it is aluminum.:Tup: Shop in OK did it for me.


fulson4 is the one who pointed me to them.

I'd like to get my hands on one of those custom carbon fiber ones.

new chevrolet trucks have carbon fiber shafts from the factory

I know a lady who owns a driveshaft shop here in FL and I asked here and she said they never reccommended them for cars with over 400hp, not sure if that is rw or crank

I think ADL here in Orlando does custom driveshafts. But idk

So, Any proof that a lighter shaft will put more power to the ground?

And if so, how much compared to stock “Heavy” steel shaft.

I like my long steel shaft, If I go aluminum it would need to be a Fat Shaft, that may not work too good off - road.

Grant's '10 Ram driveshaft is like 6" diameter and has a weird toner ring thing at the front u-joint.

:bsjerk: u seem to know how to take a shaft well :dance:


mine is light and steel.. i us paitned it to look alumunium

Anything in the drive line that is lighter, will make the vehical accelerate faster.

It may not be noticable in a 5k truck. But it's simple physics

You got it. Too bad a lot of people can't comprehend simple physics. LOL

I've always used the "rule of thumb" that for every pound of rotating mass you drop it's comparable to dropping 6lbs of dead weight. So say you get wheels that are 10lbs lighter each, it would be like dropping 240lbs off the truck.

See, thats what I was wondering, I know a lighter shaft will put more power to the ground, but is it worth it.

If my shaft weighed 100#'s, and I replaced it with a 10# shaft, then I would expect to see a difference. But we are talking about 5~10# diff, on a small diameter rotating mass, on a heavy object. If the shaft was the diameter of say, a tire, then I could see losing 5# would help, for sure if that 5# came off the outer edge of the shaft.

A lighter shaft is better, no doubt, but how much better conceding the over all weight of the truck, the small diameter of shaft, and the weight difference.

:Tup: picked up just under .2 going to a single piece aluminum shaft in my car but showed a 0hp improvement on the dyno.

It's just less Drivline loss to the rear wheels.

Someone should put a nice aluminum flexplate on their truck....

30lb steel to a 14lb aluminum would be a 96lb savings in rotational mass ill be adding one a aluminum fly wheel when and if I ever convert to a t56

do some research...when i was looking for mine i was told by several companies to stick with the steel one for the rotational mass because it was a heavy truck...now i know of one 4.7 t56 that uses aluminum flywheel, but he also has a turbo setup and his boost hits low. not sure where your hits, but he was also lighter than my truck (4220...full tank of gas, no driver) before all the modding

I dont know when the boost will come on with the superchager set up. Im reducing the hell out of weight on mine though Or better yet Trying too

Exactly.

It does NOT put more power to the ground.

It does however, require the engine to turn less weight before it get's to the tires.

I would be interested to see the gain and see if there would be any adverse effects.
