A727 Flexplate (8 Bolt)

The B and M Automotive A727 Flexplate (8 Bolt) is a precision-engineered torque converter mounting component designed for internal-balanced Mopar V8 engines paired with Torqueflite 727 and 904 transmissions. This steel flexplate meets SFI 29.1 safety specifications and accommodates 8-bolt crankshaft configurations, making it the correct OEM-equivalent choice for classic muscle cars, hot rods, and street performance builds that demand reliable power transfer without flex or slippage.

Built from high-quality steel and engineered for internal-balance applications, this A727 flexplate handles the rotational forces inherent in V8 powertrains while maintaining precise alignment with the torque converter and transmission input shaft. The 8-bolt design matches the crank geometry of compatible Mopar engines, eliminating fitment issues common with mismatched aftermarket plates. At 3.2 pounds, the component is compact and straightforward to install during engine rebuilds, transmission swaps, or routine service intervals. The SFI 29.1 certification ensures the flexplate meets stringent safety standards for high-RPM and high-torque applications.

This flexplate is essential for restorers, engine builders, and performance enthusiasts working on first-generation Torqueflite-equipped Mopars or period-correct restorations. Whether rebuilding a 1970s Dodge Charger, Plymouth Road Runner, or Chrysler muscle car, or upgrading a hot rod with Mopar drivetrain components, this part ensures secure torque converter mounting and eliminates the risk of flex or catastrophic drivetrain failure. Buyers sourcing OEM or OEM-equivalent flexplates for 727 and 904 transmissions will find this B and M component to be the direct replacement for factory specifications.
