Suncoast Converters Heavy Duty Intermediate Clutch Outer Sprag Race 34663HD-02

MIA's Description

The Sun Coast Converters 34663HD-02 is a heavy-duty intermediate clutch outer sprag race designed to improve durability in GM 4L80-E, 4L85-E, and TH400 transmissions. This part guards against sprag failure and enhances sprag element engagement and rollover resistance.

This heavy-duty sprag race is the same thickness as the OE 4L80-E and 4L85-E part, and .040" thicker than the TH400 part. It serves as a direct replacement when used with 4L80-E and 4L85-E transmissions and can be adapted for TH400 units.
