Installation Notes and Tips

Verify tooth count, outside diameter, and mounting hole diameter before installation. Confirm the vehicle’s original flexplate specifications match the listed 142-tooth, 11.929-inch design for the application. Inspect the starter, crankshaft flange, and related fasteners for wear or damage before installing the FRA-327.

For best results, compare the removed part to the new flexplate and confirm proper alignment during assembly. Because this is a precision-balanced component, careful handling during installation helps preserve balance and fitment.
