Barnett’s “Low-Profile” Lock-up Pressure Plate for 1998–’15 Harley-Davidson Big Twins (except 2013–’15 CVO/SE and 2015 FLHTC L) is specifically designed to fit under stock or aftermarket primary and derby covers. It increases the capacity of your stock clutch while keeping lever effort to a minimum—even with big-inch motors. The plate’s stainless-steel weighted arms increase pressure to the clutch progressively as rpm increase. Three sets of six coil springs (light, medium, heavy) are included for a variety of spring pressure options. The coil-spring design also provides smoother shifting and a more linear engagement compared to a diaphragm-type spring. Cable-actuated and hydraulic versions are available. Made in the USA.
