Pioneer Automotive FRA564 Automatic Transmission Flex-Plate Assembly

The Pioneer Automotive FRA564 is a direct-fit replacement automatic transmission flex-plate assembly engineered to restore OEM levels of performance. With a 12-9/16 inch (320mm) outer diameter and a 1-1/16 inch center bore diameter, this flex-plate is precisely sized to match the original equipment specification for a straightforward installation.

The flex-plate serves as the critical rotating link between the engine crankshaft and the automatic transmission torque converter. Over time, the constant expansion and contraction of a flex-plate can result in cracks or shearing — damage that cannot be repaired and requires full replacement. The Pioneer FRA564 is built to put the drivetrain back to factory-correct operation.

Key Features:

• Manufactured to OE specifications to restore proper operation
• Constructed from high-grade steel for strength and long-term durability
• Automated welding process delivers exceptional structural consistency
• Precision-balanced to factory specifications for smooth, vibration-free operation
• Correct bolt-hole spacing and ring-gear teeth match the OE part
• Quality tested before leaving the factory
• Backed by a 1-Year Limited Warranty

Pioneer Automotive Industries has been manufacturing precision drivetrain and engine components since 1946, making them a trusted name in the automotive replacement parts industry. The FRA564 flex-plate is sold as a single unit (each).
