Flexplates are .035" thicker than stock and the starter ring is welded to both sides of the flexplate for additional strength. Constructed from a high tensile strength material these flexplates resist elongation and cracking. All 168 tooth flexplates are sized for stock 3/8" mounting bolts and can be easily drilled for 7/16" diameter high performance torque converter applications and are SFI 29.1 approved.
This adapts a TH350, TH400, 700R4, Powerglide & early 4L60E to an LS-Series engine with a short crankshaft (Most, excluding 1999-01 truck engines and LQ4/6.0 which have a 'long' crank/flat flexplate/4L80E application)
Flexplate is specific to a converter with a 10-1/2" bolt pattern (TH350) and 11.063" (stock LS trans converters) and will not bolt to 'large' converter with the 11-1/2" pattern (common to the TH400.
