Progressive 990 Sport series shock for Harley-Davidson Dyna models, featuring high-pressure monotube construction with deflective disc damping and complete adjustability via rebound, compression, preload, and ride-height controls. Built for riders who want dial-in capability without sacrificing reliability or comfort.
Fits Harley-Davidson Dyna 990 models. Verify your Dyna generation and engine displacement before ordering.
The 990 adds independent adjustment knobs for high and low speed compression, rebound damping, and preload — plus a 0.4" height eyelet. Stock shocks offer none of this.
Yes. Rebound, compression, and preload all adjust via hand-accessible knobs and eyelet. No dyno or computer required.
The high-pressure monotube and deflective disc damping are tuned for consistent feel through the full stroke, which typically improves bump compliance and stability.
No — you can dial them in yourself using Progressive's tuning guide, or work with a suspension shop for a custom baseline.

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.
