Flexplate 168T STD LS

The ALLSTAR PERFORMANCE Flexplate 168T STD LS is a 168-tooth steel flexplate engineered for internal balance LS-series GM engines. This one-piece seal flexplate serves as the critical mechanical coupling between the engine crankshaft and the torque converter in automatic transmission systems, absorbing rotational forces while maintaining precise engine-to-transmission alignment.

The 168-tooth configuration is the OEM standard for LS-series engines, ensuring proper starter engagement and transmission compatibility. The internal balance specification means this flexplate is matched to internally balanced crankshafts, a distinction critical for vibration control and longevity. Steel construction provides the rigidity and durability required to handle the torque loads characteristic of modern LS powerplants. The one-piece seal design eliminates multiple gasket points, reducing potential leak pathways and simplifying installation while improving reliability over time.

This flexplate is essential for engine builders, transmission rebuilders, and serious enthusiasts constructing or rebuilding LS-powered vehicles—whether for street performance, track applications, or restoration work. It's specified when replacing a worn or damaged original flexplate, upgrading to a different transmission type on an LS engine, or ensuring OEM compatibility during a complete engine swap into a vehicle designed for LS integration.

ALLSTAR PERFORMANCE is a recognized manufacturer of engine and driveline components for performance and racing applications. The Flexplate 168T STD LS is manufactured to direct OEM specifications, making it suitable for both original equipment replacement and performance builds where proven compatibility is non-negotiable.
