40278-09 Replacement Cush Drive Dampener Rubbers

If you are noticing excessive driveline lash or vibration during acceleration, it might be time to replace your cush drive dampeners. These replacement rubber dampeners from V-Twin are designed for the rear wheel pulley on Harley-Davidson Street and Touring models. They serve as a direct replacement for OEM 40278-09. These rubbers are essential for absorbing the shock loads between the rear sprocket and the wheel hub, protecting your transmission and providing a smoother ride. Over time, the original rubber can harden or perish, leading to a sloppy feel in the throttle response. Installing these high-quality replacements restores that factory-fresh feel to your bike's final drive system.
