Stock shocks offer none of this.\u003c\/p\u003e\n\u003ch3\u003eCan I adjust these shocks without special tools?\u003c\/h3\u003e\n\u003cp\u003eYes. Rebound, compression, and preload all adjust via hand-accessible knobs and eyelet. No dyno or computer required.\u003c\/p\u003e\n\u003ch3\u003eWill these help my ride quality on rough pavement?\u003c\/h3\u003e\n\u003cp\u003eThe high-pressure monotube and deflective disc damping are tuned for consistent feel through the full stroke, which typically improves bump compliance and stability.\u003c\/p\u003e\n\u003ch3\u003eDo I need a professional to set up the 990 shocks?\u003c\/h3\u003e\n\u003cp\u003eNo — you can dial them in yourself using Progressive's tuning guide, or work with a suspension shop for a custom baseline.\u003c\/p\u003e\n\u003ch2\u003eCalifornia Proposition 65 Warning\u003c\/h2\u003e\n\u003cp style=\"font-size:11px;color:#888;\"\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e Cancer and Reproductive Harm — California Prop 65 (Y). www.P65Warnings.ca.gov\u003c\/p\u003e","brand":"Progressive","offers":[{"title":"Default Title","offer_id":53040152608879,"sku":"T14-614160","price":1896.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/6734\/6543\/files\/output_3da47fad-7c87-4dff-924e-c78e3b92e295.png?v=1779565638","url":"https:\/\/vtwinbikers.com\/products\/progressive-990-shocks-harley-davidson-dyna-990","provider":"Vtwinbikers","version":"1.0","type":"link"}
