TCI Hardened Input Shafts

4.0 out of 5 stars 8 Customer Reviews

These TCI hardened input shafts have increased lubrication, flow, and strength, a resized diameter that provides optimum stress lubrication along the entire length of the shaft, and extended high-gear splines to the oil ring. They will require some minor machining of the stator support.
