Product Description

The TCI 399773 is a black steel automatic transmission flexplate with a 168 tooth ring gear, external balance, 6 bolt crankshaft circle, 1-piece rear main bearing application, dual converter bolt pattern, and SFI 29.1 approval. It is built for applications that require an externally balanced plate rather than an internal balance setup.

This stamped Chevy-style flexplate is 0.035 in thicker than stock, with the starter ring welded to both sides for added strength. High tensile strength material helps resist elongation and cracking, while the extra-thick construction is precision balanced and checked for runout.

The external balance, 1-piece rear main bearing fitment, and dual converter pattern are the key details that separate this SKU from similar TCI flexplates. It is intended for stock to mild performance applications where SFI approval and stronger construction are required. Warranty coverage is limited to 30 days for racing use and 90 days for street or strip use.
