Product Details
When you're out on the open road, especially on a Harley-Davidson, the last thing you want is for every little crack and seam in the pavement to jar you. These Progressive 444 Series Shocks are designed to smooth out those imperfections, giving you a more comfortable and controlled ride whether you're cruising down the highway or navigating city streets. They fit a wide range of Harley-Davidson models, including popular bikes like the Road King, Street Glide, and Electra Glide.
What sets these shocks apart is their patented Frequency Sensing Technology (FST). This advanced system allows the shocks to automatically adjust their damping based on the frequency of bumps they encounter. Hitting a small ripple? The oil flows through specific ports to soak it up. Encountering a larger pothole? The oil distribution changes again to handle the bigger impact. This means you get a consistently comfortable ride without having to manually adjust anything. Plus, the top-mounted threaded preload adjuster lets you fine-tune the suspension by hand, no special tools required. You can choose between standard or heavy-duty spring rates and a sleek black finish to match your bike's style.
These shocks are well-built in the USA and come with a limited lifetime warranty, giving you peace of mind. They feature a progressive rate spring and a deflective disc valving system for improved performance. If you're looking to significantly improve your ride quality and handling on your Harley-Davidson, these 444 Series shocks are a solid option.
