TCI 29.2 Lightweight Flexplates For BBC/SBC & GM LS Applications Offer Heavy-Duty Strength, Less Weight

Ashland, MS – A new one-piece flexplate from TCI offers heavy-duty strength with less weight for high-RPM Small and Big Block Chevrolet, as well as GM LS, applications.

The SFI 29.2-certified flexplate is made from 4140 forged steel and features a hobbed-on ring gear and laser-welded converter spacers. Gas nitriding provides for extra surface hardness and strength, while CNC-milled pockets and lightening holes reduce the flexplate’s rotating mass and drop overall weight. The SBC/BBC flexplate weighs just 5.3 pounds, while the LS flexplate weighs 6.11 pounds. E-coating offers corrosion protection.

Built to withstand 12,000-plus RPM, the flexplate is a heavy-duty OEM replacement that accepts a converter with LS1 or Small or Big Block Chevrolet bolt pattern.
