618-30-20036 Scorpion lock-up pressure plate

For riders already running a Barnett Scorpion clutch on their 1936 to early 1984 Big Twin, this lock-up pressure plate is a serious performance addition. It features six weight-adjustable pressure arms that use centrifugal force to increase clutch engagement as engine speed rises. This ensures that your clutch can handle high-horsepower builds on the street or the strip without slipping. Because of the added mechanical components, please be aware that this unit will not fit inside a stock primary housing. It is a professional-grade component designed to give you maximum control over your engine's power delivery.
