Yokes

On the transmission side, Mark Williams manufactures yokes from 4340 alloy steel forgings, which are CNC machined and heat treated to 200,000 PSI tensile strength.  Optimum performance is assured by machining the splines and U-joint centerlines perfectly concentric to the spline pitch diameter.  Additionally, yokes are available for use with transmissions employing roller bearing tailhousings.  These have hardened shafts, and precision-ground o.d. compatible with Liberty, Jerico and G-force boxes, as well as needle bearing-equipped Dedenbear type tailhousings for Powerglides.

(Rapid Release Yokes)

MW also offers a "Rapid Release"series of yokes that feature removable steel caps that can be used when space limitations prevent installations with traditional yokes.  The cap design also does an excellent job of securing the U-joint cups.
