Flexplates

The flexplate connects the engine’s crankshaft to the torque converter in an automatic transmission, transmitting power while dampening vibrations. A worn or cracked flexplate can cause starting issues, noise, and transmission damage, so choosing the right replacement is essential.

  • Fitment factors: Match tooth count (commonly 153 or 168), engine balance (internal vs. external weight), and converter bolt pattern to your vehicle.
  • Construction: Standard replacements use stamped steel; high-performance flexplates feature thick chromoly or forged steel for strength under high-stall torque loads.
  • Certification: SFI-rated flexplates meet strict safety standards for racing and high-performance applications.
  • Inspection tips: Check the ring gear teeth for wear and the center hub for cracks. Always use new bolts and torque to specification.

Whether you’re restoring a daily driver or building a race car, our flexplate selection covers a wide range of transmissions and engine platforms.
