Well, if you modify the hell out of the truck, a Denny's driveshaft wouldn't hurt!

 

As I stated above - I am seriously considering it.
One the rotating mass will be less and I think the runout and
balance will be better than my stock steel one.
Esp the rear one - that is my major concern.
Us big trucks have to worry about 2 driveshafts...

 

where you pick them driveshafts up at?

 

Denny's - they build custom alum driveshafts

 

can i get a grand slam meal with it?

 

Grand slam meal, HA HA!

The driveshaft I got was almost identical in weight to the factory unit, but it is thicker, stronger, and balanced for like 8000rpms, which is like 170mph for our trucks to run that high. My vehicle smoothed out, compared to stock, and at 100 and above mph, my truck is much smoother!

 

...hodgeee, cmon now, really..... Denny's?

 

Huh. This is scary stuff.

I have a rather nasty driveshaft vibe at super-legal speeds. (definitely not the wheels)

Think it's worthwhile to pull the driveshaft and have it re-balanced, or just go for something that's built to handle this stuff?

I have the large diameter (coffee can) aluminum driveshaft, for what it's worth.

 

DENNY'S right next to Bob's Big Boy in Detroit. They are actually one block away from the company that makes our stock driveshafts!

 

detroit!... so there must be a website.... i'll look. thanks!
