SunCoast Zero/Neutral Balance Duramax Billet Flexplate 2001+

Zero or Neutral Balance Flexplates are used when all the balancing is contained within the crankshaft counterweights. This form of balancing is only common in ultra high performance applications. These applications typically have billet crankshafts.

NOTE: A SFI certified flywheel flex plate is re- quired on drag racing vehicles running 11.99 and quicker in the 1/4 mile and 7.49 and quicker in the 1/8 mile, or any vehicle exceeding 135 mph. It was changed in 2008 from the 29.1 SFI specification to the SFI specification 29.3 for automatic transmission flex plates for diesel applications. The new rules for the flex plate requires that the material cannot be a stamped metal as are many OEM and after market flex plates. To maintain the SFI specification 29.3 requirements, the flex plate must be replaced every three years.
