XACT Prolite Flywheel GM LS Series 1997-04

The XACT Prolite Flywheel GM LS Series 1997-04 from Advanced Clutch Technology is designed for LS engine builders and performance enthusiasts who require lightweight, SFI-certified components that enhance throttle response and reduce parasitic losses. This flywheel is ideal for street, strip, and track applications where performance is critical.

Constructed from premium chromoly steel, the XACT Prolite features internal balance geometry that maintains crankshaft harmony without external counterweights.
