The TCI Premium Series Flexplate for GM transmissions replaces stock Big Block Chevy 454 CI externally balanced units with a 10.75 bolt pattern and 168-tooth count.
TCI’s Premium Series transmission flexplates are designed as an upgraded replacement for factory units. Precision manufactured and featuring a premium finish that resists corrosion from salt and road grime, they’re a more durable and longer lasting option than commonly available “budget” flexplates. Spin balanced to ensure vibration-free operation for both internally and externally balanced engines, they are the perfect replacement for any stock to mild performance vehicle.
