On most applications the yokes are commonly in phase when the yoke ears are parallel to each other. So for longer driveshafts, you can increase the diameter of the shaft, change the material to aluminum or composite, or resort to a two piece shaft which is inherently prone to start up shudder. It is interesting to note that an excessive torsion of the drive shaft can have negative effects on valve timing and lead to incorrect phasing. If the yokes are not in phase, speed fluctuations will not be cancelled out. By Jim Clark, Hot Rod M.D. Connecting the two sections of the driveshaft is a center support bearing, which is a "U" shaped metal bracket with a solid-rubber machined bearing on the inside.
