608-30-20036 Scorpion lock-up clutch kit

The Barnett Scorpion lock-up clutch kit is the ultimate upgrade for high-performance 1936 to early 1984 Big Twin models. Sold as a complete kit, it fits directly into your stock clutch housing but offers significantly more holding power than a standard setup. The standout feature is the adjustable lock-up pressure plate, which uses six weighted arms that apply more pressure as RPM increases. This centrifugal design means the harder you ride, the harder the clutch bites, making it ideal for both aggressive street use and the drag strip. You can even use lighter springs to reduce lever pull without sacrificing performance.
