Yella Terra YT9912R Heavy-Duty Billet Flexplate for Holden and Nissan RB30
The Yella Terra YT9912R is a heavy-duty billet steel inertia flexplate developed for high-performance Holden and Nissan vehicles powered by the RB30 3.0-litre SOHC inline-six. Designed specifically for the factory Jatco four-speed automatic transmission, it provides a stronger and more stable replacement for the original pressed-steel flexplate in demanding street, drift and drag-racing applications.
High-output RB30 turbo engines place substantial torsional load through the crankshaft, flexplate and torque converter. The YT9912R's billet steel construction is intended to improve reliability and resist the fretting associated with factory-style pressed flexplates, while its relatively low rotating mass supports responsive acceleration.
