Auto Transmiss Parts FRA-203HD Heavy-Duty Automatic Transmission Flexplate 157-Tooth Ford

The FRA-203HD is a heavy-duty automatic transmission flexplate designed as a direct-replacement for Ford vehicles equipped with automatic transmissions. Flexplates (also called flex plates) are critical drivetrain components that connect the engine crankshaft to the torque converter, transferring rotational power from the engine to the transmission and ultimately to the wheels.

This heavy-duty unit is based on the proven FRA-203 platform, featuring a 157-tooth ring gear and an outer diameter of approximately 13.294 inches, matching OE dimensions for a precise, bolt-on fit. The ring gear teeth engage the starter motor to crank the engine, while the bolt pattern secures directly to the torque converter.

Key Features:

• Heavy-Duty Construction — upgraded steel build for enhanced durability over standard-duty versions
• 157 Ring Gear Teeth — matches OE tooth count for proper starter engagement
• 13.294-inch Outer Diameter — OE-matched dimensions for direct fitment
• External Balance — 28 oz. external imbalance specification for correct Ford engine balance
• Bolt-On Installation — torque converter bolt pattern with 10.5-inch diameter, 4-hole equally spaced at 7.424-inch pattern
• Center Hole Diameter: 1.75 inches
• Flywheel Pitch: 12–14
• Steel Construction — built to withstand the constant stress and flex cycles of normal operation

Flexplates are subject to cracking, tooth wear, and stress fractures over time, especially under high-load or high-RPM conditions. The FRA-203HD heavy-duty variant is the ideal replacement when a more robust solution is required. Broken or damaged flexplates cannot be repaired and must be replaced to prevent further drivetrain damage.
