Flexplate- As performance levels increase, a standard flexplate just won’t cut it and a stronger option is a necessity to prevent transmission and/or converter failure. RTS has you covered with our upgraded standard OE styled flexplates, designed for transmissions which are internally or externally balanced. These flexplate assemblies are zinc plated and heat treated with a chromate conversion coating for added corrosion resistance and durability. They will get your vehicle back on the road and are great for cars producing low to intermediate power levels. Available in standard or SFI 29.1 certified versions.
