The "Beast" Reaction Sun Shell

The reaction sun shell is a highly stressed component in the gear train of the 700-R4 and 4L60E transmissions. The "Beast" sun shell is made from thicker material the the OEM shell, and has a much thicker, heat treated hub with a generous radius to reduce stress at the splines.

-Recommended for all heavy duty and high performance applications

-100% drop-in part

-Retrofits all 700-R4, 4L60E and 4L65E transmissions

-Comes with special thrust washer to accommodate additional radius at the hub

We use this sun shell exclusively in all Stage 2 and higher transmission builds and build packages.
