Progressive Harley 444 Series Shocks 13.0in - Chrome

The patented Frequency Sensing Technology (FST) in these Progressive 444 Series shocks is a notable design choice. It means the shocks can automatically adjust their damping based on the frequency of bumps encountered on the road. Whether you're dealing with small road imperfections or larger impacts, the oil inside the shock is directed through specific ports to absorb the hit, leading to a more comfortable ride. These shocks are designed to fit a wide range of Harley-Davidson Dyna models, including popular bikes like the Street Bob, Fat Bob, and Wide Glide.

You can fine-tune the spring preload by hand, without needing any special tools, thanks to the top-mounted threaded adjuster. This allows you to dial in the suspension to your specific riding style and load. These shocks come with a progressive rate spring and a reflective disc valving system, further contributing to their ability to handle varied road conditions. They are available in different configurations to suit your needs, including standard weight and heavy-duty spring rates, and this particular model features a bright chrome finish.

These 13-inch shocks are a well-built upgrade for your Harley-Davidson, offering a blend of advanced technology and user-friendly adjustments. They are backed by a Limited Lifetime Warranty and are made in the USA, giving you confidence in their durability and performance for years to come.
