Steel or Aluminum Driveshaft?

[WhtMa71]

i would say 2 piece but how do u upgrade a stock 2 piece? ... i think any 1 piece will vibrate nomatter what meterial

Shaftmasters makes an upgraded 2piece.

2 piece is a little safer if you plan on making sustained high-speed runs.

for high speeds i would think a 2 piece is good.
Racing all these's little srt-4 like to go past 120mph lol pretty fast little cars but i cant beat one that has a upgraded turbo with aem tune making 435:cry: to the wheels that's my rival since high school....2 piece!!!!:biglaugh:

i have a shaftmasters 1-piece aluminum and have had no problems whatsoever up to 145mph. no vibrations.. in fact less vibrations compared to stock since the carrier bearing had so much play
i havent hit the drag strip since i got it or sustained speeds in excess of 120mph for more that 2 minutes so i dont know of the long term effects

i think the lighter the driveshaft the more it vibrates cuz its lighter... the weight keeps it from moving ....correct me if im wrong?

Incorrect.

Hell the correct answer is in the music world. Look at any STRINGED instrument.

The thicker/heavier guage strings will always be lower in frequency than the lighter/thinner strings.

Guitar
Piano
Violin
Cello


the lighter the weight, the higher the frequency of the harmonics. The opposite is also true (heavier wieght, the lower the frequency of the first order harmonics).

well okay i was way off!! i still dont know which one to go for

Be sure to replace the transmission gasket behind the driveshaft (I didn't....stupid stupid stupid) and also use a torque wrench on the bolts for the differential flange. Otherwise it'll vibrate until it loosens up a bit, which is what mine did. Perfectly fine now, and the bolts are still tight.

Noticeable difference in acceleration.

torque stick? are you talking about a torque wrench?

A friend and I just replaced my clutch and now I have HORRIBLE vibration at first take off. The clutch was broke in properly. I got back under there and verified that all was in order. Everything is in the right place and all is tight. Unless I missed something.

I'm beginning to wonder if the carrier bearing and/or u-joints were on the edge of going bad and the removal and re-install pushed them over the edge.

Does anyone know how much play is too much in the carrier bearing?

Anyone experience similar issues?

Oh...and how long will a new clutch smell like it's burning with normal driving?
