The TCI 145300 is a Chrysler Torqueflite flexplate for 426 ci HEMI engines. It is a forged flexplate for 426 HEMI engines mated to Torqueflite transmissions, with SFI 29.1 approval and internal balance.

This SKU is built around the exact 426 HEMI and Torqueflite application rather than a generic flexplate listing. The small bolt circle, 7/16 in bolt detail, and 8-hole forged crank fitment help the buyer verify the application before ordering.

TCI notes this as the only flexplate they offer for 426 HEMI and Torqueflite transmissions. Confirm the 426 HEMI engine, Torqueflite transmission, small bolt circle, and 7/16 in bolt requirement before installation.

The TCI 242950 is a bolt-together triple-disc torque converter for 4L80E and 6X applications. It uses woven-carbon friction material, lock-up control technology, a CNC-machined billet front, pre-hardened steel construction, a billet turbine hub, lock-up piston, and 50-spline clutch hub.

This converter is built for demanding high-stall applications with a 3000 to 3200 RPM stall range. The removable billet front gives service access to the lock-up assembly, turbine, stator, and bearings for future servicing or re-stalling when the vehicle combination changes.

TCI notes that no single-disc option is available for this converter. For accurate stall range, TCI recommends checking the full vehicle setup, including weight, engine displacement, power adders, rear gear ratio, and tire diameter.

The TCI 221100 is a TH400 full manual valve body with a reverse shift pattern. It is built for competition use where the driver controls the valve body manually rather than relying on automatic shift timing.
