Heavy-duty billet flexplates from TCI® are like no other option on the market. This SFI 29.2 certified, one-piece LS version is designed for GM Gen III and Gen IV engines. It is made from a CNC-machined 4140 forging with a hobbed-on ring gear and laser-welded converter spacers and can withstand more than 12,000 RPM. The flexplate is gas-nitrided for extra surface hardness and strength, and then e-coated for corrosion protection. Lightening holes reduce rotating mass and drop the overall weight to 7.6 pounds. The design features multiple bolt patterns and is exclusive to TCI® 

For serious performance, TCI machined SFI-approved flexplates are a "must have". These .140 in. thick flexplates are constructed of A514 Blanchard ground steel and are SFI 29.1 approved.
