Suncoast ALLISON LB7/LLY/LML BILLET FLEXPLATE

LB7/LLY/LML/L5P BILLET FLEXPLATE

This replaces the factory flywheel/flex plate with an improved billet steel one-piece design and eliminates the heavy cast iron and the weak stamped steel flex plate. This is a must with the high torque in conjunction with a better-designed torque converter that can transfer the torque with no slip.

The flex plate is bolted to the crankshaft and then the converter is bolted to flex plate. The torque from the motor is transferred to the flex plate, then goes from the flex plate to the torque converter and finally to the input shaft in the transmission. With increased torque from the engine, it can crack and/or rip the center out of a stock flex plate.

NOTE: An SFI-certified flywheel flex plate is required 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 require that the material cannot be a stamped metal as are many OEM and aftermarket flex plates. To maintain the SFI specification 29.3 requirements, the flex plate must be replaced every three years.
