Detailed Description

Pioneer Cables FRA-441 is an OE-style replacement flexplate for vehicles that require a 138-tooth, 11.688-inch outside diameter design. The plate measures 296.863 mm in diameter and uses 8 mounting holes with a 9.37 mm mounting hole diameter. This flexplate is built for automatic transmission applications where correct tooth count, bolt pattern, and balance are critical to smooth engine-to-transmission operation. This part cross-references Ford service numbers such as F77Z6375AA and FM254M for the same application.

Use FRA-441 when servicing a Ford Ranger flexplate, Mazda B4000 flexplate, or Mercury Mountaineer flexplate application that calls for the listed dimensions and tooth count. The part is not SFI approved and does not include an SFI certification sticker.

What This Flexplate Helps Address

• Cracked or warped flexplate surfaces
• Starter engagement issues caused by worn or incorrect tooth count
• Engine vibration related to imbalance
• Noise from damaged flexplate teeth or mounting points
• Transmission service needs where the original flexplate is no longer usable

Installation Notes and Tips

Verify tooth count, outside diameter, mounting hole quantity, and pitch before installation. Confirm vehicle coverage by year and engine/transmission configuration for your Ford Explorer, Ford Ranger, Mazda B4000, Mercury Mountaineer, or Ford Aerostar application. Inspect the starter, crankshaft flange, and fasteners for wear or damage before installing the new flexplate. Proper torque procedures and final balance checks are important for reliable operation.
