Flexplate 168T SFI External Balance 86-up

The Flexplate 168T SFI External Balance 86-up from Allstar Performance is designed for serious engine builders and high-performance enthusiasts who require reliability in demanding applications. This flexplate is essential for connecting your engine and transmission, effectively managing the rotational forces produced by modern powerplants while ensuring perfect balance under extreme conditions.

Engineered with external balance characteristics, this 168-tooth flexplate is compatible with engine combinations that necessitate external balancing through a dedicated harmonic balancer and counterweight system. The SFI certification guarantees that this component meets Society of Automotive Engineers standards for safety and performance in competitive environments, making it a reliable choice for sanctioned drag racing and engine dyno work.

Weighing 7.33 pounds and with a diameter of 14.7 inches, the flexplate's robust construction is capable of handling the torsional loads imposed by aggressive shifting, converter stall speeds, and sustained high RPM operation without flex or deflection that could compromise driveline harmony. This flexplate is suitable for applications from 1986 and later, where engine displacement, stroke length, or performance modifications require external balancing.
