TCI Automotive Chevrolet 1-Piece Rear Main SBC (1986-1999) ; External Balance; Dual Bolt Pattern

TCI Chevy stamped flexplates are .035" thicker than stock, and the starter ring is welded to both sides of the flywheel for additional strength. Constructed from a high tensile strength material, these flywheels resist elongation and cracking. All 168-tooth flywheels have GM dual bolt patterns, are sized for stock 3/8" mounting bolts and can be easily drilled for 7/16" diameter high performance torque converter applications. These machined flexplates are perfect for stock to mild performance applications.
