TCI Standard SFI 29.2 Flexplate (GM LT1 & LT4)

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.

• Lightweight version - 6.09 lbs; Standard version - 7.6 lbs
• Built to withstand 12,000+ RPM
• Heavy-duty OEM relacements accept six-bolt LT1 and LT4 converters
