ever heard good thing about this driveshaft?

What about the Roush trak pak driveshaft? I hear those can be had for pretty cheap as they are being cleared out.

i have been on roush's website many times, and never seen a driveshaft offered? i just looked now too. :shrug: have a link? i would like to pick one up cheap. :D
 
I installed my coast shaft about a year and a half ago in my garage, and made about 200 1/4 mile passes with it. Haven't had one problem with it, the car feels smoother and I picked up about 2 tenths at the strip. Money well spent .

2 piece shaft?

WHY,,,fords better idea... our family buisness was driveshafts,,,after my 20yrs of fixing and making them ,,i say it thier for viberations,,,chevy tryed with the camaro,,no luck ,,,i also have been out of the buisness for 10 yrs now and have only seen pictures of the new shaft,,,lol for hours,,,,im also still vote for steel (steel vs alum) FWIW they are all ok , for your own research The Expert - Librarian - Information for driveshafts, u-joints, axles, heavy axles, light axles, Driveline
 
As I understand it, we have two-piece driveshafts. Why? I thought only trucks with really long drive shafts needed two-piece to keep from whipping.

Easy. The S197 and 2004+ F150 are notorious for being very touchy to vibrations. The two piece driveshaft helps cut down on vibrations. Tons of people do not have problems with an aluminum one piece driveshaft though.
