Product #: 223601B

Turbo 400 Billet Steel Forward Drum & Billet Input Shaft (with Modified Lube Circuit)

TCS has introduced a NEW INPUT SHAFT for the Turbo 400 that has the torque converter lube holes removed from the shaft to deliver superior strength. 

  • Drum is machined from 4140 HTSR billet steel.
  • Input shaft is made from 300 Maraging steel.
  • Shaft to drum spline count has been increased from 30 to 35 splines for extra contact and strength.
  • Overall drum & input shaft weight is 2.50 lbs lighter than the OEM drum & shaft with major weight reduction on the O.D.
  • The input shaft is permanently located in the drum by a shoulder stop and snap ring.


To use the "modified lube circuit" input shaft assembly, the bushing in the stator tube must be removed plus the converter must have a bushing for the turbine.
