TCS Fat (27 Spline) Magnum Billet Input Shaft (20199132200)

27 spline magnum billet input shaft (fat shaft) for 47rh, 47re, and 48re transmissions.  If your high-powered diesel street or race truck regularly destroys the standard sized (23 spline) 300m, 300maraging, or AerMet billet input shafts, upgrade to this 27 spline Magnum shaft!  This is the strongest shaft we have tested and is used exclusively for all 1000 HP Power Driven Transmissions.  This 27 spline shaft is 10% wider than the 23 spline (stock sized) billet shafts and requires a modified pump stator (bored 0.100″ larger) and 27 spline (magnum) torque converter.  Modified pump stators are available for purchase, or we can machine/bore out your old pump stator to fit the magnum fat shaft.
