Built for extreme-duty applications, these flexplates are designed to withstand the demands of today’s high-horsepower engines. A 4mm-thick centerplate provides a robust foundation, while precision-welded ring gears—crafted using advanced robotic cold-welding techniques—meet stringent SFI specifications. Each PRW Power Flexplate is engineered for peak performance and undergoes rigorous quality inspections throughout the manufacturing process, ensuring the durability and reliability our customers have come to expect.
