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 shock is engineered to deliver a superior riding experience for Harley-Davidson owners. It stands out as one of the most adjustable rear shocks available in the V-Twin market, offering precise control over your suspension.
Designed for riders who demand the ultimate in suspension performance, the Progressive 990 Sport series shock allows for extensive tuning. Independent adjusters for high-speed and low-speed compression damping, along with rebound damping and preload, are all easily accessible via hand knobs. This means you can dial in your ride to perfection, whether you're tackling aggressive corners or enjoying a long-distance cruise.
At its core, the 990 Sport series shock features a high-pressure monotube design coupled with deflective disc damping. This combination ensures a consistent feel and stable performance throughout the entire suspension stroke, translating to improved handling and stability on your Harley-Davidson. The linear rate coil spring and captured jounce bumper further enhance the ride quality, absorbing road imperfections while maintaining composure under load. Elevate your ride with a shock that truly responds to your demands.
Can I adjust these shocks after installation without removing them?
Yes, all major adjustments including high/low-speed compression, rebound damping, and preload are designed to be accessible via hand knobs once the shocks are installed on your bike.
What kind of difference will these shocks make to my ride?
You can expect significantly improved handling, increased stability, and a more comfortable ride due to the precise control over damping and preload, allowing you to tune for various conditions.
Are these shocks compatible with my specific Harley-Davidson model?

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.
