Thomson's Flexplate Solution
GM Performance Parts' LSX454 crate engine and the supercharged LSA crate engine each use a crankshaft with an eight-bolt rear hub that doesn't match the standard six-bolt pattern of conventional GM automatic transmission flexplates-including the popular Hydra-Matic 4L80-E. To address this issue, Thomson Automotive designed a flexplate kit that features a factory GM eight-bolt flexplate and a custom-machined adapter hub. The flexplate is also modified to accommodate the bolt patterns of popular aftermarket torque converters.
