    Description

    TCI Automotive 399860LW - Designed for high-RPM GM LT1/LT4 engines, this SFI 29.2 certified 1-piece flexplate withstands 12,000+ RPM. Weighing significantly less than a factory unit, this lightweight flexplate delivers more power by reducing rotating mass.

    One-piece flexplates from TCI offer heavy-duty strength with less weight for high-RPM GM LT1 and LT4 applications. Available in standard and lightweight versions, the TCI SFI 29.2-certified flexplates are made from 4140 forged steel and feature a hobbed-on ring gear and robotic tig-welded converter spacers. Gas nitriding provides for extra surface hardness and strength, while E-coating offers corrosion protection. CNC-milled pockets and lightening holes reduce the flexplate’s rotating mass and drop overall weight.
