Progressive Harley 444 Series Shocks 11.0in - Black

The patented Frequency Sensing Technology (FST) in these Progressive 444 Series shocks is a notable design choice, allowing them to dynamically adjust damping based on the frequency of bumps encountered. This means the shocks can distribute oil through their ports differently whether you're dealing with small road imperfections or larger impacts, leading to a more comfortable ride across varied conditions. These shocks fit a wide range of Harley-Davidson Sportster models, including popular bikes like the XL1200X Forty-Eight and the XL883N Iron 883.

Beyond the FST, these shocks feature a progressive rate spring, which offers a softer initial engagement for comfort and stiffens up as you go deeper into the suspension travel, providing better support during hard riding. You can easily fine-tune the spring preload by hand using the top mount threaded adjuster, eliminating the need for special tools. They also incorporate a deflective disc valving system for consistent damping performance. These shocks are well-built in the USA and come with a limited lifetime warranty, reflecting Progressive's commitment to durability and rider satisfaction.

When ordering, consider the weight capacity you need. The 444 Series is available in Standard Weight, Heavy-duty for riders over 250 lbs, and Super Heavy Duty specifically for Touring models over 350 lbs. This particular model is 11.0 inches in length and features a black finish.
