Pioneer Cables FRA-544 Flexplate Overview

The Pioneer Cables FRA-544 is an automatic transmission flexplate built as a direct replacement for OE-style performance restoration. It is manufactured from high-grade steel, formed to original dimensions, welded with an automated process for consistent strength, and precision balanced to factory specifications.

With 135 teeth and an 11.25-inch outside diameter, this flexplate is engineered for Ford and Mercury applications that require accurate starter engagement and stable rotational balance. The FRA-544 is a practical choice for transmission service on select Ford Ranger, Ford Explorer, Ford Explorer Sport Trac, Ford Mustang, and Mercury Mountaineer models.

Key Features

  • Automatic transmission flexplate for OE-style replacement
  • 135-tooth ring gear for starter engagement
  • 11.25-inch outside diameter
  • 0.938-inch diameter specification
  • 12-pitch flywheel specification

Detailed Product Description

Pioneer Cables FRA-544 is designed for drivers and repair shops looking for a replacement automatic transmission flexplate that matches original dimensions and balance requirements. The steel construction, welded assembly, and factory-spec balancing help maintain proper drivetrain operation in vehicles that rely on a 135-tooth flexplate layout. This part number, FRA-544, is also referenced for the same application as AA-F265.

Fitment includes 2002-2011 Ford Ranger, 2002 and 2003-2006 Ford Explorer, 2007-2010 Ford Explorer, 2002-2005 and 2007-2010 Ford Explorer Sport Trac, 2007-2010 Ford Mustang, and 2002-2010 Mercury Mountaineer. For Ford Ranger and Ford Explorer service, the tooth count and outside diameter should be verified against the vehicle’s original flexplate before installation.

What This Flexplate Helps Address

  • Cracked or fatigued flexplate material
  • Starter engagement issues caused by worn ring gear teeth
  • Vibration from an out-of-balance flexplate
  • Transmission service needs on Ford Ranger, Ford Explorer, and Ford Mustang applications
  • Replacement of a damaged OE-style automatic transmission flexplate

Installation Notes and Tips

Confirm the vehicle’s original tooth count, outside diameter, and flywheel pitch before installation. This FRA-544 flexplate is listed with 135 teeth and an 11.25-inch outside diameter, while some listed Ford and Mercury applications note 138 teeth and a 11.625-inch outer diameter, so matching the exact engine and transmission configuration is essential. Inspect the starter, crankshaft flange, and related drivetrain components during service to ensure proper fit and engagement.

Quality Assurance

Pioneer Cables manufactures this flexplate from high-grade steel and balances it to factory specifications for consistent replacement quality. The automated welding process is used to improve strength and repeatability across production.
