Have any 99-04 single cab trucks come with factory aluminum driveshafts? In wanting to get every hundreth out of the truck for the southern shootout i think it may be benificial to reduce some rotating mass. Wil it be worth it to change or not? Its so easy to change I figure it wouldnt hurt.

 

It will help some but how much is the question.

 

I got a 4" aluminum driveshaft from a 3/4-ton G20 van. It's set up for 1350-series joints, so you'd have to get new u-joints and such. It measures 70" long...

Here are some pics:

 

Thats a sweet shaft. I wonder how much it would cost to get one lengthened to fit an extended cab.

 

Hows the 80E swap going by the way?

 

Lengthing is not very cost effective but shortening on is.

 

80-e swap is still on the garage floor. Just waiting to get a little more $ together and get the rear end done at the same time so I can run 1350-series joints all the way through, including the yoke on the rear end.
