How many of you extended cab guys have a 1 piece driveshaft. I have a friend that had a bad vibration problem in his 4x4 HD. He had it in the shop 4 times with all the standard fixes. Then they finnally replaced his 2 piece with the one piece. You guys think there is any advantage to this? Strength or otherwise?

 

I have pondered the same question. The two piece drive shaft has to eat-up more horsepower that a single one but I dont know how much. Hopefully someone else will chime in.

 

My HD came with one. I had it out the other day. It only weighs about 20-25 lbs. It was very light.

 

I thought all short bed ext. cab 4x4s had one piece aluminum drive shafts. With the transfer case its not all that long. My drive shaft is about 6 feet long, but if I could find a good light weight one piece I wouldnt mind swapping.

 

FAST !!
Great question and idea.
Especially for us lowered guys
Do think Dennys Driveshaft would be able to chime in ?
Give use some advise ?
My shaft look so weak compared to my composite '91
I'm interested

 

I spoke with Dennys early last year about it. At the time, all they offered was a 2 piece. Makes sense about the transfer case. Forgot about that. May be time to contact Denny's again.

 

i've installed about 30 of those things to elimiate the 2 piece version. they are much lighter and keep the driveline angles more consistant which was a huge problem. they fixed the launch shudder condition on almost every case i installed them in, took some un-needed weight off the truck, and added a bit more power at the wheels. very good mod usually under warrenty. although it doesn't state it in the bulletin, i've also done it on a couple 03's. the bulliten number for those who want to check it out is: 01-04-17-001B.

 

Greg - you have a vib problem ????
I had one as soon as I put the 2" shackles on
before I went to the 2/4

I have not driven it yet with the 2/4
Waiting on the front springs - frt end is apart

 

hey zippy where did you get the shaft at and where do we go to check the bulliten????

 

Alum or composite
Where did you get it
Cost
Were all you did this mod on 2wd ?
