The FTI BA Series crankshaft pilot adapter sleeve converts a GM-style interface to Ford engine dimensions, specified for a 1.375 inch crankshaft pilot. It is intended for drivetrain adaptation where a pilot adapter is required to match crankshaft diameters between engines and torque converters, allowing reuse of components across GM and Ford engine pairings when that exact pilot size is needed.
