Experience a comfortable and confidence-inspiring ride - no matter the pavement conditions - with Harley-Davidson® Premium Ride Emulsion Shocks. These fast shocks offer enhanced compression and rebound damping control when compared to typical twin-tube shock absorbers. The nitrogen gas charged shocks resist oil aeration and work with the internal valve stack to provide superior damping control in the twisties. The large pistons and low viscosity high-performance oil allow these shocks to react quickly to impacts and keep the tires tracking the road surface. With the addition of urethane bumpers, you get a controlled ride and minimized bottoming harshness. The locking threaded adjustment lets you fine tune the spring preload to your current riding conditions - whether a solo run on the back roads or a fully-loaded two-up freeway tour. Kit includes left and right shock and preload adjustment spanner wrench.
