Yella Terra YT9927 Heavy-Duty Billet Flexplate for Six-Bolt LS Engines
The Yella Terra YT9927 is a heavy-duty billet steel flexplate for high-performance Chevrolet and Holden LS-series engines with a six-bolt crankshaft. It is designed for tough street cars and drag-racing applications using popular GM automatic transmissions, providing a stronger and more stable alternative to factory-style pressed flexplates.
Its billet steel construction helps resist the fretting and distortion that can develop under high engine torque and repeated converter loading. The YT9927 is neutral balanced, uses a 168-tooth ring gear and incorporates multiple torque-converter bolt patterns for compatible 4L60E, 4L80E, 6L80E, TH350 and TH400 combinations.
