Ford Coyote Flexplate '11-'17 5.0 SFI 29.1

The Ford Coyote Flexplate '11-'17 5.0 SFI 29.1 is a precision-engineered flexplate designed for Gen 1 and Gen 2 Coyote 5.0L engine swaps and high-performance builds. This component serves as the critical interface between your engine's crankshaft and automatic transmission, absorbing rotational forces while allowing controlled flex to dampen vibration and shock loads. Whether you're building a modern restomod, upgrading a late-model Mustang, or executing a complete powertrain conversion, this SFI-certified flexplate ensures reliable power transfer and compliance with sanctioning body standards for street and competition use.

Manufactured by PRW Industries—a trusted name in performance engine components—this flexplate features SFI 29.1 certification, meaning it meets stringent safety standards for controlled failure in high-stress environments. The 29.1 rating indicates this plate has been dynamically tested and rated for increased RPM and torque loads, making it ideal for forced-induction applications, nitrous systems, or built engines producing elevated horsepower. At 8.82 pounds and measuring 14.5 x 1.5 x 14.5 inches, it integrates seamlessly with 2011–2017 Ford Coyote 5.0L platforms, providing the structural integrity needed to handle aggressive acceleration and sustained power delivery without flex-related wear or premature failure.

This flexplate is essential for anyone performing a Coyote engine swap into a classic chassis, upgrading transmission components on a modern Mustang, or building a competition-ready platform. Compatibility spans 2011–2017 Ford Coyote 5.0L engines paired with automatic transmissions, and its SFI certification ensures you meet tech inspection requirements at drag strips, autocross events, and sanctioned racing venues. Installation requires proper balancing and verification of flexplate runout; working with a qualified machine shop ensures optimal concentricity and eliminates vibration issues. For street or strip duty, this PRW Industries flexplate delivers the durability and performance margin required to protect your investment and keep power flowing reliably to the wheels.
