RACING DAMPER - Part Number 98-474
Put more glide in your ride! * Helps your engine rev faster. * Lengthens crankshaft life. * U.S.A. Made. * Easy to install (minor modifications needed on some models). Racing dampers counteract the vibrations created by the uneven firing impulses of the H-D V-Twin engine, freeing the engine to create more usable horsepower since less energy is eaten up by the vibration. The reduction in vibration solves other problems -- handlebar & footpeg vibration, mirror shake and rider fatigue. Comes complete with installation instructions; very easily installed by loosening of the compensator sprocket nut. NOTE: Not recommended for Big Twin with 61 tooth rear belt pulley.
