Overview

The Sun Coast Converters COA-22747A Lightened OEM Reaction Carrier is a race-inspired upgrade designed to significantly enhance the responsiveness of Turbo Hydramatic 400 (TH400) transmissions. By precisely reducing the rotating mass within the internal gear train of the standard OEM carrier, this component delivers faster torque response and improved throttle feel. Manufactured in the USA under Coan's exacting standards, the COA-22747A ensures structural integrity while boosting performance. This part is ideal for street/strip builds, bracket racers, and high-demand applications where a quicker, more responsive drivetrain is desired. Installation requires the complementary COA-32430 bearing to ensure smooth operation and prevent premature wear. It installs directly into standard TH400 cases with no machining required, maintaining seamless integration with stock or Coan performance components.
