Description

LS Flexplate Adapter

This LS flexplate adapter supports GM LS Gen III/IV engine swap combinations that use an earlier GM automatic transmission and matching torque converter setup. The steel construction and included mounting hardware help establish the correct crankshaft-to-converter spacing for the transmission combinations noted in the fitment section.

Use it when the LS crankshaft, flexplate, torque converter, and transmission require added spacing for proper converter pilot engagement. Confirm crank length, flexplate offset, converter depth, and transmission model before installation.
