    Here are some strong, affordable flexplates for you guys running 289/302/351W small block Ford engines. Built from high-tensile chromoly steel, these flexplates are SFI approved and .035" thicker than stock pieces.

    Double welded ring gears will withstand the torque generated from high-stall converters, while the lightweight design promotes rapid engine response. The 157-tooth flywheels are available in 28 or 50 oz.

    Due to the unique offset of these flexplates, they will not work in conjunction with an OEM 12" torque converter.

    • SFI approved
    • Direct bolt-on component
    • Balanced and checked for runout
    • Lightweight design for rapid engine response
    • Constructed from a high tensile strength steel
