This flex plate is designed to allow Mopar Gen III Hemi engines (5.7L, 6.1L, 6.2L, and 6.4L) to be paired with GM automatic transmissions when using compatible aftermarket torque converters. Rather than relying on welded spacers for converter spacing, this flexplate is formed to the correct offset, providing a cleaner, purpose-built solution. It is engineered around aftermarket converter bolt patterns commonly used by manufacturers such as Gear Star, making it suitable for performance and swap applications where correct converter fitment is critical. Fitment should always be confirmed by converter bolt pattern, not transmission model alone, as many aftermarket converters use unique patterns.

Gen III to swapped bellhousing GM trans only, with aftermarket (small circle) converter.
