The all new Barnett “Low Profile” Lock-up Pressure Plate for 1998-13 Harley Davidson Big Twins (except 2013 CVO/SE) is specifically designed to fit under stock or aftermarket primary and derby covers and increases the capacity of your stock clutch while keeping lever effort to a minimum- even with big inch motors! It’s done by using stainless steel weighted arms that progressively increase pressure to the clutch as RPM’s increase. Three different 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. Installation is bolt on with no modifications required. Whether you’re looking for a lighter clutch effort for a stock Big Twin or serious no-slip performance for a big inch motor, the Barnett Low Profile Lock-up Pressure Plate has got you covered all in one attractive, precision machined unit! Cable actuated and hydraulic versions are available. MSRP: $475
