GM Performance Parts Flexplate/Crankshaft Adapter/Spacer

Product images may differ from actual product appearance.

This crankshaft spacer is used when installing a transmission built before 1997 to a LS1-type motor. The LS design small block crankshaft flange is 10mm shorter in relation to the end of the bell housing flange. If using a small block automatic transmission built before 1997, there will be a 10mm gap between the crankshaft and torque converter when the bell housing is bolted to the block. This will require a flexplate spacer to adapt older small block automatic transmissions to the LS1-type engine. The LS1 flywheel is reused, and it goes on before the spacer. Torque converter bolt holes in the flywheel must be elongated to fit the non-LS1 torque converter bolt circle.
