Brand New TCI GM Chevy LS Engine 6-bolt Crankshaft SFI Flexplate with 10.75" and 11.062" Converter Patterns and Converter Pilot Extension (Part #399753).

SFI 29.1 approved. Fits most LS-series Gen III and Gen IV Chevy 4.8, 5.3, 5.7, 6.0, 6.2 and 7.0 litre V8 engines using a 6 bolt crankshaft flange. Drilled for 10.75" small GM converter bolt pattern and also 11.062" (281mm) LS style converter bolt pattern. Includes a converter pilot adapter that is needed if you are using a converter originally made to fit older small or big block Chevy (non-LS). Flexplate is .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 this flexplate resists 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. Fits both LS transmissions and older Powerglide, TH350, 700R4, transmissions and converters behind LS engines. For 4L80E or TH400 applications that have an 11.5" torque converter bolt pattern, use P/N 399754.

Notes: This will not fit 1999-2000 6.0L applications with 0.400 in. extended crank flange and came with flat flexplate. | This will not fit 1999-2000 4.8L applications that originally came with a manual transmission.
