Progressive Suspension has focused exclusively on American V-twin suspension since 1982, and its Monotube fork cartridges and 400/970/970G shock series are among the most common upgrades on baggers and Softails. For most riders the stock rear shock is the single worst part on the bike — this is the fix.
Progressive 444 Series shocks for Harley-Davidson feature advanced Frequency Sensing Technology (FST) that dynamically adjusts damping in real-time. This innovative system ensures that your V-twin absorbs both small road imperfections and larger impacts with equal composure, delivering a consistently smooth and controlled ride. With options for spring rates and finishes, you can tailor these shocks to your specific needs.

The shocks seem super nice, but they are incredibly stiff. Turns out they’re 130/200 top to bottom. Would be nice to have an option to choose your spring rate. Couldn’t find it in the description either. Have them installed on a 1998 sportster 1200 by the way. I’m about 180lbs and they don’t move at all, my friend who weighs about 260 also said they were way to firm. Hope this helps.
