TH400 Heavy Duty Input Shaft
For use with turbine support bushing in converter.
Input shaft failure is a common problem in performance GM TH400 transmissions running with added horsepower. OE and aftermarket shafts simply don’t hold up in these conditions, leading to spline twist and shaft breakage.

This shaft is intended for use with aftermarket converters with internal turbine supportIts. Its forward drum spline is designed to be used with aftermarket drums with compatible 28-tooth spline, including Sonnax heavy duty forward drum 34554-01 and Smart-Tech® drum module 34555-01K.
