Brand New TCI Chevy LS Engine 6-bolt Crank SFI Flexplate 11.5" GM Pattern w-Pilot Ext (Part #399754).

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 11.5" wide GM converter bolt pattern using 6 holes. Includes a converter pilot adapter that is needed if you are using a converter originally made to fit older small or big block Chevy (non-LS).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.

Fits TH400 and 4L80E transmissions and converters behind LS engines. For 4L60 or TH350 applications that have an 10.75" or 11.062" torque converter bolt pattern, use P/N 399753.
