The TCI 145300 is a heavy-duty automatic transmission flexplate for popular Chrysler, Ford, and Chevy applications. TCI offers this style as a stamped stock-replacement flexplate option for builders who need a stronger drivetrain service part than a basic replacement.

For Chrysler cast crank applications that originally used a counter-balanced torque converter, TCI notes special counter-balanced flexplates that allow the use of a neutral-balance torque converter. That makes this type of flexplate useful when converter balance requirements need to be corrected as part of the transmission setup.

Because the available information is broad, the exact vehicle, engine balance, and converter balance requirements should be confirmed before purchase. The important buyer point is matching the flexplate to the correct Chrysler, Ford, or Chevy application rather than treating it as a universal part.

The TCI 529610 is a black steel automatic transmission flexplate with a 157 tooth ring gear, 50 oz external balance, 6 bolt crankshaft circle, 10-1/2 in torque converter bolt circle, and SFI 29.1 approval. It is balanced specifically for its Ford engine and transmission combination.

TCI stamped flexplates are built 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 extra-thick construction is precision balanced and checked for runout.

This flexplate supports 1-piece and 2-piece rear main bearing applications where the listed 50 oz balance and 157 tooth ring gear are required. The black steel construction, SFI approval, and precise Ford balance details are the key buyer checks before purchase. Warranty coverage is limited to 30 days for racing use and 90 days for street or strip use.

The TCI 399754 is a black steel automatic transmission flexplate with a 168 tooth ring gear, internal balance, 6 bolt crankshaft circle, 1-piece rear main bearing application, 11-1/2 in converter bolt circle, and SFI 29.1 approval. It is built for applications requiring a neutral internally balanced flexplate with that converter pattern.

This flexplate uses A514 Blanchard ground steel and 0.140 in thickness for moderate to serious performance applications. The heavy-duty plate resists elongation and cracking, while welds on both sides of the starter ring help strengthen the ring gear area.

Precision balancing and runout checks support accuracy for a rotating drivetrain component. The 11-1/2 in converter bolt circle is the key differentiator versus similar TCI 168 tooth flexplates. Warranty coverage is limited to 30 days for racing use and 90 days for street or strip use.

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.

The TCI 399273 is a black steel automatic transmission flexplate with a 168 tooth ring gear, internal balance, 6 bolt crankshaft circle, 2-piece rear main bearing application, and SFI 29.1 approval. It uses 10-1/2 in and 11-1/2 in torque converter bolt circles for applications that require those converter patterns.

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

The internally balanced setup and 2-piece rear main bearing fitment are the key differentiators versus similar TCI flexplates. It is intended for stock to mild performance applications where SFI approval, stronger material, and correct converter pattern matching matter. Warranty coverage is limited to 30 days for racing use and 90 days for street or strip use.

The TCI 399753 is a black steel automatic transmission flexplate with a 168 tooth ring gear, internal balance, 6 bolt crankshaft circle, 1-piece rear main bearing application, and SFI 29.1 approval. It uses 10-3/4 in and 11.062 in torque converter bolt circles for applications that require those converter patterns.

This flexplate is built for moderate to serious performance use with A514 Blanchard ground steel, a 0.140 in thickness, and neutral balance construction. The heavy-duty plate resists elongation and cracking, while welds on both sides of the starter ring add strength around a high-stress area.

The flexplate is precision balanced and checked for runout before use. It is also built extra thick with the ring gear welded on both sides, preserving the official strength and accuracy details that matter for a rotating drivetrain component. Warranty coverage is limited to 30 days for racing use and 90 days for street or strip use.
