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 990 Sport series shocks represent the pinnacle of V-Twin suspension technology. These shocks offer an unmatched level of adjustability, putting you in complete command of your ride's dynamics.
Engineered for discerning Harley-Davidson riders, the Progressive 990 Sport series shocks are designed to provide a truly custom-tuned experience. With independent adjustments for high and low-speed compression damping, rebound damping, preload, and even ride height, you can fine-tune every aspect of your suspension directly from the rider's seat.
At the core of the 990 Sport series is a high-pressure monotube design combined with advanced deflective disc damping. This technology ensures a consistent feel and stable performance across the entire suspension stroke, absorbing bumps and maintaining traction with precision. The lightweight aluminum body and linear rate coil spring contribute to a responsive and controlled ride, making these shocks a top choice for any Harley-Davidson owner seeking a significant suspension upgrade.
Can I adjust these shocks while they are on the bike?
Yes, all major adjustments including high/low-speed compression, rebound, preload, and ride height are designed to be easily accessible and adjustable from the rider's seat.
Will installing these shocks affect my motorcycle's ride height?
These shocks feature a 0.4 inch adjustable height eyelet, allowing you to fine-tune your motorcycle's ride height to your preference.
Are these shocks compatible with my Harley-Davidson?
These shocks are designed for Harley-Davidson models. Please verify fitment with your specific year and model using our Shop by Bike tool before ordering.

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.
