Pro Series Flexplate SFI 29.1 Gen 3 Hemi

The PRW Industries Pro Series Flexplate SFI 29.1 Gen 3 Hemi is engineered for serious enthusiasts and mechanics building or rebuilding high-performance Mopar Gen III Hemi engines. This heavy-duty flexplate serves as the critical mechanical bridge between your engine's crankshaft and automatic transmission, absorbing rotational stress while maintaining precise engine timing. Whether you're restoring a classic Dodge, upgrading a Challenger, or tuning a performance build, a quality flexplate is non-negotiable for reliability and longevity.

Constructed from premium steel with internal balance specifications, this Pro Series flexplate features 131 teeth for reliable torque converter engagement and is rated to SFI 29.1 safety standards—critical certification for high-horsepower applications where flexplate failure can cause catastrophic damage. The one-piece seal design eliminates common leak points at the crank interface, reducing maintenance headaches and fluid loss during aggressive acceleration. At 7.39 lbs, this flexplate delivers the strength required for forced induction, nitrous, or naturally aspirated big-block performance without unnecessary weight penalty.

This flexplate is purpose-built for Gen III Hemi engines found in 2003-and-later Dodge trucks, Challengers, Chargers, and performance platforms using Mopar automatic transmissions. Internal balance compatibility ensures smooth operation on freshly blueprinted or stock short-blocks, and the SFI certification guarantees it meets sanctioning body standards for drag racing, street performance, and dyno testing. Professional installers and DIY builders alike trust PRW Industries' Pro Series components for their durability under sustained high-RPM and high-torque conditions.
