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 990 Sport Series shocks for Harley-Davidson feature a high-pressure monotube design with deflective disc damping. This advanced setup provides complete adjustability via accessible knobs and hand-threaded controls, ensuring consistent damping through the stroke.
These shocks are engineered to deliver improved performance and stability on the road, allowing you to fine-tune your ride for any condition. The lightweight aluminum body and linear rate coil spring contribute to responsive handling and a precise feel.
The Progressive 990 Sport Series shocks are for riders who demand maximum control and tunability from their suspension. With multiple adjustment points, you can dial in your Harley-Davidson's handling to suit aggressive riding, touring, or anything in between. Experience a new level of confidence and comfort on every ride.
Can I adjust these shocks without special tools?
Yes, the Progressive 990 Sport Series shocks feature external knobs and hand-threaded controls for high and low-speed compression, rebound damping, and spring preload, allowing for tool-free adjustments.
What is the benefit of adjustable compression and rebound damping?
Adjustable compression allows you to control how quickly the shock compresses, while adjustable rebound controls how quickly it extends. This lets you fine-tune the shock's response to bumps and improve overall handling and stability.
Will these shocks fit my specific Harley-Davidson model?
These shocks are designed for Harley-Davidson models. It is crucial to verify your specific year and model using our Shop by Bike tool or by consulting Progressive's fitment guide to ensure correct application 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.
