Lock Up Clutch Kit - '99-'17 Big Twin

• Specifically designed to fit under the stock or aftermarket primary/derby covers and increase the capacity of your stock clutch by using stainless steel weighted arms that progressively increase pressure to the clutch as rpm increases
• This also allows lever effort to be kept to a minimum - even with big-inch motors
• Three different sets of six coil springs (light, medium, heavy) are included for a variety of spring pressure options
• Coil spring design provides much smoother shifting and a more progressive, linear engagement compared to a diaphragm-type spring
• Simple bolt-on installation is all that is required with no modifications needed
• Made in the U.S.A.
