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.
The Progressive 944 Ultra Low shocks with Quik Preload System (QPS) are designed to provide a smooth, controlled ride for Harley-Davidson Touring models while lowering the bike's stance. Featuring Frequency Sensing Technology (FST), these shocks automatically adapt damping to various road conditions. The QPS allows for rapid preload adjustments, making it easy to switch between solo and two-up riding without the hassle of removing saddlebags.
Unlock superior handling and a custom lowered look for your Harley Touring or Softail. These Progressive 944 Ultra Low QPS Shocks are engineered to deliver consistent performance across diverse riding scenarios. The advanced damping system reacts dynamically to bumps, ensuring comfort and stability, while the quick preload adjustment system offers unmatched convenience for riders who carry varying loads.
Whether you're cruising solo or loaded down with a passenger and gear, these shocks ensure your Harley remains composed and comfortable. The ease of adjustment means you can quickly dial in the perfect setup for any situation, enhancing both ride quality and safety. Invest in a suspension upgrade that performs as hard as you ride, transforming your V-twin's capabilities on the open road.

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.
