With valve train stability being our main concern we manufacture all of our shafts to be very stiff. Our choice of material is .250” wall thickness 4130 Chromoly steel. Each heat treated shaft is prepared in a four axis milling center, then center less ground undersize, hard chromed oversize and finish ground to size. This leaves a hard chrome surface, providing excellent wear protection in any application, including use in your daily driven street Hemi. All of our shafts use a threaded plug to seal each end. This eliminates any chance of an oil leak from worn or poor fitting O-rings.
