What This Flexplate Helps Address

Installation Notes and Tips

Verify tooth count, outside diameter, and flywheel pitch before installation. Confirm the application matches your Jeep Cherokee, Comanche, Wagoneer, or Wrangler by year and transmission configuration. Inspect the starter, torque converter interface, and mounting surfaces for wear before installing the FRA-333. Proper alignment and torque procedures are important to maintain balance and reduce drivetrain vibration.
