TCI Automotive Dual Pattern Flexplate for Chevrolet Small/Big Block 399870

Description:

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 Big and Small Block Chevy engines. It is made from a CNC-machined 4140 forging with a hobbed-on ring gear 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 6.8 pounds. The design features multiple bolt patterns and is exclusive to TCI .
