No rider input needed.\u003c\/p\u003e\n\u003ch3\u003eCan I adjust preload without special tools?\u003c\/h3\u003e\n\u003cp\u003eYes — the top-mount preload adjuster twists by hand. Simply turn the cap to increase or decrease spring tension.\u003c\/p\u003e\n\u003ch3\u003eWhat's the difference between standard and heavy-duty spring rates?\u003c\/h3\u003e\n\u003cp\u003eStandard rate suits typical rider weight and cargo. Heavy-duty is for heavier riders or frequent two-up and luggage loading.\u003c\/p\u003e\n\u003ch3\u003eDo I need to revalve or service these shocks regularly?\u003c\/h3\u003e\n\u003cp\u003eProgressive shocks are sealed and maintenance-free. Inspect mounts and hardware annually, but internal servicing is not required during the warranty period.\u003c\/p\u003e\n\u003ch3\u003eAre these made in the USA?\u003c\/h3\u003e\n\u003cp\u003eYes — Progressive manufactures these shocks in the USA.\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":53040148578415,"sku":"T14-614091","price":860.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/6734\/6543\/files\/output_014d4ecf-3389-4ce2-a303-c293eaa08801.png?v=1779565568","url":"https:\/\/vtwinbikers.com\/products\/progressive-444-shocks-harley-davidson","provider":"Vtwinbikers","version":"1.0","type":"link"}
