Description

Part #: 399853

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.

This forged flexplate is for 4.8, 5.3, 5.7 and 6.0 LS series engines. SFI 29.2 approved and internally balanced. Small and LS Bolt pattern with 168 tooth count.
