Well, just thought all should know that I weighed the DS and the result was 23 lbs. At 3"s, this is such a better deal than the 4" alum. shafts that everyone talks about. Less rotational mass, stronger, and costs the same. What morecould you want. Now can't wait to get it on!

how much does the stock DS weight and how much does the 4" alum one weight?

 

I have not weighed the stock shaft myself. ( have not removed it yet) I have read that it weighes approx. 45 lbs. The 4" alum. shafts weigh 16-17 lbs. But they are 4" instead of 3" and less strength.

I assume the 3' is steel?

 

I have had the Denny's in for a few weeks with 0 problems. It is an awesome shaft. It is high speed balanced to 8000 rpms, so there is no vibration issue. It has a lifetime warrwnty against breakage. It is their "nitous proof" steel 3" shaft. I had a different 3.5" chromemoly in before this one, and had vibration issues no matter what I did.

 

how much of a difference would it make in acceleration wise on the 1/4?

 

I've heard the 4inch alumnum driveshafts that weigh 16-17lbs reduce et's by .2 in the 1/4 mile

 

Did I miss something along the way? Who makes this 3" DS? What is the "same" cost?

Never mind I just saw the topic "Weighed the Denny DS".

 

Waiting for driveshaft prices to come down to reasonable levels. Maybe if and when FRPP starts offering one.
