Boss Hog Outlaw Flexplates
Flexplates serve as crucial links between engine and automatic transmission, connecting the engine's crankshaft to the torque converter, then transmitting power to the transmission. They're designed to flex, allowing the torque converter to float and absorb engine vibrations, preventing potential damage to the transmission. Installing a higher stall torque converter, or making an improvement that increases your engine's horsepower or torque, requires a flexplate upgrade as well.
Boss Hog Outlaw flexplates deliver incredible performance and are ideal for high performance builds. Available in options to fit numerous applications, each Outlaw plate is crafted from steel and has an SFI 29.1 rating. Upgrade your flexplate to handle the increased power load; select a Boss Hog Outlaw.
