Product Description
An input clutch hub for 45RFE, 5-45RFE and 68RFE transmissions. TCS machines it from 4140 heat-treated, stress-relieved billet steel rather than the factory cast version, which has a known weak spot at the input shaft spline area; this hub provides greater strength at that spline area.
It is a 100% drop-in part, and no modifications are necessary.
