PRW LS Swap Multi-Pattern SFI Flexplate

PRW Pro Series Flexplates set a new standard in the high-performance industry. Built for extreme-duty applications, these flexplates are designed to withstand the demands of today’s high-horsepower engines. A 4mm-thick centerplate provides a robust foundation, while precision-welded ring gears—crafted using advanced robotic cold-welding techniques—meet stringent SFI specifications. Each PRW Power Flexplate is engineered for peak performance and undergoes rigorous quality inspections throughout the manufacturing process, ensuring the durability and reliability our customers have come to expect. 

Converter Bolt Pattern: 3 x 10.75" GM,  3 x 11.0" GM, 3 x 11.50" GM, 6 x 11.06" GM, 6 x 11.50"
Transmission Bolt Patterns Included: TH350, TH400, 700R4, 4L60E, 4L80E

Fitment Note: When mating an LS engine to a TH400 transmission using this flexplate, a crank sleeve adapter is required to properly support the torque converter snout. We recommend using PRW PN 1800346.
