Speedway Motors flexplate / flywheel for the LS Gen III 4.8/5.3/5.7/6.0 (1997-2001). Listed for one application: LS Gen III 4.8/5.3/5.7/6.0 engines, 1997-2001, in Chevrolet, GMC, Pontiac, Cadillac applications. Confirm your engine code and year against this listing before ordering.

What it does

The flexplate connects the crank to the torque converter and carries the ring gear the starter engages. Cracked flexplates knock at idle and grind on start; the wrong bolt pattern or offset will not bolt up. A new plate with the correct pattern and ring-gear tooth count restores quiet starts.
