Mark Williams 4" Aluminum Driveshaft

Mark Williams 4" Aluminum Driveshaft Product Description:

Mark Williams new aluminum driveshaft features advance Duralcan® material. Material content increases yield strength by 28% and elasticity by 41%, which in turn, increases the critical shaft speed (the RPM at which the shaft will go into harmonic vibration and risks self destruction). Torsional wind-up is reduced which can have a profound improvement on reaction times. MW end yokes produced from aluminum alloy are 30% stronger than the competition! Balancing weights attach to yoke rather than to the tube.

4" (less Yoke) includes U-Joints

Should be ordered with yoke for proper balancing.
